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...

Abstract Nanostructured bio-adsorbents were prepared by physical or chemical activation of the residue supercritical extraction raspberry seed. Their physicochemical properties determined elemental analysis, low-temperature nitrogen adsorption/desorption, Boehm titration and scanning electron microscopy. The biocarbon obtained as a result precursor showed basic character surface its S BET was 7...
