A facile and highly porous heterogeneous matrix was designed as a support for zero-valent Cu nanoparticles. This heterogeneous support is composed of filter paper, chitosan, and titanium dioxide, and on this support matrix, a metallic Cu2+ nanoparticle was loaded. The metallic Cu2+ nanoparticle was then reduced to Cu0 in NaBH4 solution The prepared catalyst (Cu/CHTiO2/FP) was characterized by X-ray diffraction (XRD), Fourier transforms IR spectroscopy (FTIR), scanning electronic microscopy (SEM), energy-dispersive X-ray spectrometry (EDS), and energy-dispersive X-ray spectroscopy (XPS) and the results indicated that the synthesis of zero-valent Cu nanoparticles on the heterogeneous support by this method was successful. The prepared Cu/CHTiO2/FP catalytic activity was investigated to remove four different textile dyes: Rhodamine B, Bromocresol Green, Methyl orange, and Eriochrome Black T in the presence of NaBH4. The results show that the catalyst is efficient and can be adapted to remove the different classes of dyes studied. Aside from the catalyst’s efficiency, it could be quickly recovered by simply pulling out from the reaction medium, washed, and reused. The reusability of the catalyst recorded over 90% removal after five cycles.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about Removal of Bromocresol Green from aqueous solution by electro-Fenton and electro-Fenton-like processes with different catalysts: laboratory and kinetic model investigation, the main research direction is bromocresol green aqueous solution kinetic model.Synthetic Route of C21H14Br4O5S.

This study presents the removal of triarylmethane dye Bromocresol Green from aqueous solution by the electro-Fenton process. As catalysts five different cations were used: Fe2+, Ce3+, Ni2+, Mn2+, and Co2+. They play crucial roles in the whole process because they react with H2O2 producing hydroxyl radicals that are capable of breaking down dye mols. Based on this, a comparison of catalytic activity of these cations in the electro-Fenton process is made for Bromocresol Green degradation A simple and universal kinetic model is also applied to study the catalytic activity of investigated catalysts. Due to its multidimensionality it is fitted to exptl. data using a genetic algorithm. The procedure of fitting using a genetic algorithm is thoroughly described and demonstrated. The activity of utilized catalysts is compared based on both exptl. and model data revealing that for Bromocresol Green removal all alternative catalysts (Ni2+, Co2+, Ce3+, Mn2+) are better than the typical one (Fe2+, 51.83% degradation). The best catalyst is Co2+ with 78.35% degradation efficiency. Moreover, the adopted kinetic model proved its universality and outlined different interactions between catalysts and dye mols.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Silver nanoparticles incorporated in dicarboxylic/TEPA modified halloysite nanotubes for the degradation of organic contaminants, published in 2020-11-30, which mentions a compound: 76-60-8, mainly applied to silver nanoparticle dicarboxylic acid TEPA halloysite nanotube organic contaminant, Product Details of 76-60-8.

Silver supported on organo-modified halloysite nanotubes (Ag-HNTX/T) were fabricated through three steps of modifications; (i) functionalization of pristine halloysite nanotubes (HNT) with dicarboxylic acids, namely succinic acid (SA), oxalic acid (OX), or sebacic acid (SB), (ii) addition of tetraethylenepentamine (TEPA), and finally (iii) incorporation of silver particles (Ag). The modification with dicarboxylic acid and TEPA on HNT was proven by the presence of -COOH and -NH functional groups in the FTIR spectra. Upon introduction of Ag particles on the organo-modified HNT, the Ag-HNTSA/T sample exhibits UV-DRS absorption at 460 nm, corresponding to the presence of Ag particles with the average size of 12.1 ± 6.5 nm. The HRTEM result reveals that Ag particles are deposited on the surface and inside the lumen of HNT, which is in-line with slight decrease in SBET attributed to some pore blocking in Ag-HNTSA/T. The catalytic activity of the fabricated Ag-HNTX/T (X = SA, OX or SB) was evaluated through the borohydride-assisted degradation of organic contaminants, i.e. methyl orange (MO), methylene blue (MB), p-nitrophenol (p-NP), and bromocresol green (BG). The Ag-HNTX/T catalyst exhibited excellent catalytic activity and the process follows the pseudo-first order kinetics. The Ag-HNTX/T possesses sustainable catalytic performance up to 15 recycled applications.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about Ligand binding to natural and modified human serum albumin.Application In Synthesis of 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide.

This paper reports evaluation of ligand binding constants for unmodified or biotinylated HSA (HSAB) for two well-known HSA binding ligands, naproxen and bromocresol green. Results demonstrate differential scanning calorimetry (DSC) is a reliable quant. method for straight-forward and rapid evaluation of ligand binding constants for HSA and modified derivatives DSC measured the thermodn. stability of free and ligand-bound HSA and HSAB at pH = 6.0, 7.4 and 8.0. DSC anal. provided a quant. gauge of responses of HSA and HSAB thermodn. stability to ligand binding. The influence of different levels of biotinylation of HSAB on ligand binding, and how ligand binding varied as a function of pH for these mols. was also examined In the three pH environments, biotinylation increased stability of HSAB alone compared to free HSA at pH 7.4. Stabilities of free protein and ligand-bound complexes varied with pH in the order, pH = 6.0>7.4>8.0. Our anal. approach provided very accurate estimates for known binding constants of these ligands for HSA. Results revealed, for both ligands, extent of biotinylation of HSAB affected binding, reducing binding constants from three to 100-fold. DSC anal. was able to delineate inter-relationships between mol. structure and thermodn. stability of HSA and HSAB bound by ligands; and their variations with pH.
