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

نویسندگان

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...

Removal of chromium (VI) from aqueous solution by adsorption using cousinia eryngioides boiss and activated carbon

Adsorption capacity of Cr (VI) onto cousinia eryngioides boiss, activated carbon was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH, temperature, agitation speed, absorbent dose and particle size. Cr (VI) removal is pH dependent and found to be maximum at pH 2.0. The amounts of Cr (VI) adsorbed increased with increase...

Phenol Removal from Aqueous Solutions by Adsorption on Activated Carbon of Miswak’s Root Treated with KMnO4

Background and Purpose: Phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. In this study, an activated carbon of Miswak’s root (MR) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. Materials and Methods: Adsorption exper...
