Efficient adsorption of some substituted styrylpyridinium dyes on silica surface from organic solvent media – Analysis of adsorption-solvation correlation

Adsorption of a Styrylpyridinium Dye on Silica and Modified Silica Surfaces from Some Binary Solvent Mixtures─Should We Call It Solvent-Induced Preferential Adsorption?

“…The adsorption of C 12 -NMe 2 dye onto the surfaces of unmodified and modified silica adsorbents in neat solvents has recently been studied. − Successful evaluation of the solvatochromic and substituent effects on the adsorption capacity of UnMS, GOMS, and SDSMS for the extraction of the cationic dyes from various organic media of differential polarities including ethanol, dioxane, and toluene has been reported in the reported studies. All the studies show strong influences of solvent on the adsorption capabilities of the various categories of silica samples.…”

“…The aqueous solution of silica gel was boiled under continuous stirring for 4 h, filtered, and dried at 95 °C for 48 h in an air oven. Finally, the purified silica gels were stored in a dry place for future use . All organic solvents (Spectrochem, India) were distilled before application.…”

“…Finally, the purified silica gels were stored in a dry place for future use. 11 All organic solvents (Spectrochem, India) were distilled before application. The silica surface was modified with graphene oxide 12 and sodium dodecyl sulfate 13 to obtain GOMS and SDSMS, respectively.…”

“…Worldwide consumption of DS is approximately 1443 tons [1]. Owing to the huge production and usage of DS globally, it is frequently detected in surface water [2,3]. DS can result in toxic biological effects and microbial drug resistance of different living organisms in water and even cause toxic effects on aquatic and terrestrial ecosystems, thereby posing a great threat to the environmental and human health [4,5].…”
