Enhanced adsorption of arsenic using calcined alginate

Mar 15, 2019· The calcination process enhanced adsorption kinetics due to the large surface area, which improved the overall adsorption performance of the adsorbent in the column although adsorption capacity in the batch isotherm decreased slightly. Therefore, the calcination process could solve the limitation of alginate bead, that is, slow adsorption kinetics.

Enhanced adsorption of arsenic onto alum sludge modified

Mar 01, 2018· In comparison, calcination at 300 °C removed organic matter efficiently without changing the structure of the adsorbent, and showed greater adsorption capacity for As(V). The results suggested that calcination is a suitable process for producing alum sludge-based adsorbent for As(V) removal.

Arsenic Removal from Aqueous Solutions Using Fe3O4-HBC

Jun 26, 2014· The presence of elevated concentration of arsenic in water sources is considered to be health hazard globally. Calcination process is known to change the surface efficacy of the adsorbent. In current study, five adsorbent composites: uncalcined and calcined Fe3O4-HBC prepared at different temperatures (400°C and 1000°C) and environment (air and nitrogen) were investigated for the

Using CaO to stabilize arsenic sulfide slag by moderate

Mar 27, 2017· This study was conducted to investigate the stabilization of arsenic sulfide slag (ASS) with CaO calcinations at moderate temperature, including the effects of calcination temperature and different As/Ca molar ratios on arsenic leaching concentration. In the process of calcination for arsenic-contained waste, 90.95–97.23% of arsenic was reserved and the original waste was
