: Arsenic Removal - an overview ScienceDirect Topics

The removal of arsenic by adsorption depends on the adsorbent properties such as particle size, density, surface area, pore characteristics, mineralogy, zeta potential, characteristics of the surface functional groups, activation conditions, etc. and the solution properties such as temperature, pH, arsenic speciation, and ionic strength [46].

2014-12-1 Layered double hydroxide compounds (LDHs) have been applied for the removal of oxyanions including arsenate (As (V)). However, the aim of this present research is to develop a LDH to treat arsenite (As (III)). Both batch and column sorption studies were conducted to assess the effect of LDH dosage, contact time, solution pH and initial As (III) ...
