Removal of bisphenol S from drinking water by adsorption using activated carbon and the mechanisms involved

چکیده
Bisphenol S, an alternative chemical to bisphenol A, has a negative effect on living organisms and frequently been detected in drinking water systems. A promising cost-effective method for removing S from tap is adsorption by activated carbon. However, carbon significantly decreased the capacity of comparing with that deionized based experimental results. Dissolved organic matter was likely responsible it. The kinetics can be described pseudo-second-order model. Langmuir isotherm model well describe process, suggesting monolayer adsorption. maximum calculated as 83.19 mg g−1. Higher temperature pH were unfavorable process. Changes entropy, enthalpy, Gibbs free energy implied spontaneous exothermic Fourier transform infrared spectroscopic analysis found hydroxyl amino functional groups are main involved. research provides substantial basis understanding removal using limit direct exposure water.

Removal of fluoride from drinking water by adsorption onto Activated Alumina and activated carbon
The ability of activated alumina and activated carbon to remove Fluoride from aqueous solution has been investigated. The studies were carried out as functions of contact time, concentration and pH. The data indicate that activated alumina surface sites are heterogeneous in nature and that fits into a heterogeneous site binding model. The optimum pH for complete removal of Fluoride from aqueous...
