In this study, we aimed to observe how different operating parameters influenced the photocatalytic degradation of rhodamine B (RhB, cationic dye) and bromophenol Blue (BPB, anionic over ZnO/CuO under visible light irradiation. This further corroborated optimization study employing response surface methodology (RSM) based on central composite design (CCD). The synthesis nanocomposite was carrie...

This study examined adsorption of anionic dye on four zeolitic materials incorporated (VS-1, CuZSM-5) and not into metals (S-1, ZSM-5). The the bromothymol blue (BTB) adsorbents was analysed using isotherm models Langmuir, Freundlich, Temkin. Two kinetic were also applied to process, pseudo-first order pseudo-second order. isothermal data showed good correlation. kinetics better described by mo...

The extensive use of dyes in numerous industries results massive dye discharge the wastewater, which is a major cause water pollution. Globally, consumption near seven hundred thousand tons across different sectors, around 10–15% goes into wastewater. Among kinds, anionic make up main proportion, having 32–90% share Different plant-derived wastes, are sustainable given their natural abundance, ...

Nickel bis(dicarbollide) is used as a fast, one-electron outer sphere redox couple in dye-sensitized solar cells. Device performances with this anionic shuttle are investigated with different electrolyte concentrations and additives, using only 0.030 M of the Ni(III) bis(dicarbollide) to efficiently regenerate the ruthenium dye. Atomic layer deposition of Al(2)O(3) on the nanoparticulate TiO(2)...

Peanut hull, an agricultural waste, proved to act as an efficient adsorbent for five anionic and cationic dyes. The process was found to be a pH dependent, suggesting the adsorption is controlled by interaction between the charged dye molecule and the surface charge on the adsorbent. The effect of variable parameters (contact time, pH, mass of adsorbent, dye concentration, agitation and activat...

A 1D anionic lanthanide coordination polymer {[(CH(3))(2)NH(2)] [(H(2)abtc)(2)Ho(H(2)O)]}n () (H(4)abtc = 3,3',5,5'-azobenzene-tetracarboxylic acid) has been synthesized under hydrothermal reaction conditions. The protonated [(CH(3))(2)NH(2)](+) is generated from decomposed DMA during the reaction, and balances the negative charge of the framework. The as-obtained samples were characterized usi...
