Solubility of 2,6-diphenyl-4-(2,4,6-triphenylpyridinium-l-yl) phenolate, commonly known as Reichardt' s betaine dye and a ketocyanine dye has been determined in binary solvent mixtures and in cationic and anionic micellar media. In all the binary mixtures the standard molar free energy of solution, as given by log Sl2 where 512 is the solubility in the binary mixture, cannot be represented by t...
Recently, use of naturally-occurring low-cost and harmless material for removal of trace contaminants from colored wastewater has attracted extensive attention. In this study, silkworm pupa has been used as a basic dye adsorbent. Adsorption capacity and isotherms have been assessed. Results show that adsorption isotherms can be expressed well by Langmuir equation. The effects of parameters such...
This study was investigation employed the batch adsorption method using Bardakçı Clay/Van as an adsorbent to remove crystal violent, a cationic dye from aqueous solution. The effects of pH, amount, interaction time and concentration were investigated determine optimal conditions. conditions determined be pH=6, 0.6 g reached equilibrium at 25th minute. isotherm Langmuir, Freundlich Dubinin–Radus...
a new, local agro-industrial waste was valorized by chemical treatment and tested for its ability to remove cationic dye from aqueous solution. tendu (diospyros melanoxylon) leaves refuse, a solid waste from bidi industry which caused disposal problem, was studied as a biosorbent. raw tendu waste (tlr), along with sulfuric acid carbonized tendu waste (tlr-cm) and tendu waste treated with dilute...
