A new method based on spectrophotometry was established for detecting the trace arsenic in water. With the existence of strong acid, the trace concentrations of arsenic after concentrating by JM-33 resin reacted with disulfoantipyl methane to form a 1:2 complex which the maximum absorption wave lied at 325nm with an apparent molar absorptivity of 1.74×1041/(mol·cm). When the concentration of arsenic...
A novel, bio-based sorbent for As(III), α-Fe2O3-impregnated chitosan beads (FICB), has been successfully synthesized and tested. Batch wise adsorption experiments were performed to evaluate the adsorption conditions, reusability as well as the effect of ionic strength and coexistence of other ions. The results indicated that the maximum adsorption capacity of FICB for As(III) was 4.46 mg/g at pH 5...
Removal of as(V) and as(III) from water using hydrous cerie oxide, CeO2ldrxH2O (HCO) was investigated under different pH and As loading conditions, using batch equilibrium adsorption and FTIR methods. Adsorption of both As(V) and As(III) anions was virtually independent of pH and up to 100% removal can be achieved in the lower concentration range 0.5 - 5.0 mg L-1 As at sorbent dosage of 1.0 g L-1...
Compounds of mercury, chrome and arsenic are very dangerous to man due to their instability and their interaction with fats, providing long periods of partial ejection, i. e. the time during which half of the agent assimilated with the organism ejects or destructs. Hence, the control of mercury, chrome and arsenic content in the water is very critical. In this paper, the sorption capabilities of the...
