Chemical Research Letters, May 2021. Redox catalysis has been broadly utilized in electrochemical synthesis. The appropriate choice of redox mediator can avoid electrode passivation, which strongly inhibit the efficient activation of substrates. 26978-64-3, Name is 4-Hydroxybutane-1-sulfonic acid, molecular formula is C4H10O4S.

Removal of some cationic dyes from aqueous solution by acrylamide- or 2-hydroxyethyl methacrylate-based copolymeric hydrogels
In this study, anionic hydrogels were prepared using a crosslinker (N,N’-methylenebisacrylamide) through a free radical addition reaction in aqueous solutions of neutral acrylamide or 2-hydroxyethyl methacrylate monomer and anionic monomers, mesaconic acid or aconitic acid. Cationic dyes along with safranine (azine-), nile blue (oxazine-) and methylene blue (thiazine-) were selected as models of pollutants, and adsorption of these dyes onto the hydrogels was investigated. To examine the effect of concentration on adsorption, dye solutions prepared with a concentration range of 5-50 mg l (-1) and 0.1 g hydrogel at 25 A degrees C were exposed to the hydrogels until equilibrium was established. Dye adsorption onto the hydrogels was found to be an L type Giles adsorption isotherm. Monolayer sorption capacity and adsorption constant values were calculated from the Langmuir plots. To calculate R-L values, a non-dimensional analysis was used and they were always found to be 0 < R < 1. In other words, the hydrogels were favorable for adsorption of these dyes. Aqueous solutions of dyes were observed to interact with hydrogels in the following order: oxazine > azine > thiazine. Furthermore, the higher the number of carboxyl groups in the hydrogel composition, the higher the adsorbed amount of substance.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
