摘要: Abstract In contrast to aqueous media, adsorption of some styrylpyridinium dyes with electron donating/electron withdrawing substituents on silica scaffold from organic media has been studied. The confirmed through FTIR, SEM, XPS and XRD techniques. Organic solvents have chosen a sedimentation time study, which gives an excellent correlation various solvent parameters. impacts environment, substituent, adsorbent dosage, temperature the extent rate examined along thermodynamic kinetic analyses. Second order exothermic mode observed physical suggested. Isotherm fitting data suggest monolayer formation dye molecules surface.
