Preparation and application of VOCs adsorption materials in textile industry

Abstract

Abstract A series of HMS molecular sieves with different pore structures were prepared by using dodecylamine and octadecylamine as template and tetrabutyl orthosilicate as silicon source to study the different pH values and temperatures. Adsorption performance. The physicochemical properties of HMS molecular sieves were characterized by BET, XRD and SEM. The results showed that the HMS molecular sieve material synthesized by dodecylamine as template was obtained after standing for 12 h in water bath for 12 h, pH 2 and calcination temperature was 550 °C. The best adsorption effectis HMS molecular sieve material synthesized by octadecylamine as template agent has the best adsorption effect when the aging time is water bath for 24 h, pH is 10, and calcination temperature is 550 °C. The adsorption rates are up to 71.72% and 74.78%, respectively.
