Cleaning the arsenic(V) contaminated water for safe-guarding the public health using novel composite material

With increasing arsenic contamination scenes reported around the globe, the highly promising materials are important to remove the arsenic from industrial and specified contaminated for safe-guarding the public health. In this study, we have prepared ligand anchoring inorganic-organic frameworks based well-ordered, high surface area composite materials for selective arsenic(V) (As(V)) removal from contaminated water. Adsorption studies were evaluated in batch mode with the function of pH, time, initial As(V) concentration, counter-ions and reuses by suitable eluent. Before starting the As(V) adsorption, the composite materials were protonated using 2.0 M HCl. The materials exhibited high adsorption efficiency in low pH area, however; the neutral pH region (7.0) was selected to avoid the divalent anions effect as the monovalent arsenate species were…
