The result- ing zeolite was rinsed with distilled water and dried in oven at 60 C for 24 h. After drying, the zeolite was ground till become powder form by using a mortar. of zeolite and just enough water to make a paste (around 2 tbsp. As water enters through the system, soluble iron gets oxidized. We prepared eight different prototypes of IMZ for arsenic removal and eventually used one for further testing. Dousová B, Fuitová L, Grygar T, Machovic V, Kolousek D, Herzogová L, Lhotka M. J Hazard Mater. 2014 Oct;186(10):6565-76. doi: 10.1007/s10661-014-3874-7. The process of adsorption follows first-order kinetics and the adsorption behavior is fitted with a Freundlich isotherm. Would you like email updates of new search results? Effect of sorbent dosage on arsenic removal distilled water at either 25, 70 or 90 C for 24 h. The zeolite was separated from the solution by vacuum filtration. The second material is a new formulation that consists of iron-modified zeolite (IMZ). It was shown that the filter modified by zeolite had more efficiency in arsenic removal because of higher cation exchange capacity (CEC) than any other media. In this research, a natural zeolite (clinoptilolite) was exchanged with iron(III) to enhance its As removal. 2011 Mar 15;187(1-3):318-23. doi: 10.1016/j.jhazmat.2011.01.030.

Epub 2017 Apr 13. However, the Fe-eZ was not effective to remove As from Chia-Nan Plain groundwater due to its high initial As concentration (511 μg/L), high amounts of natural organic matter, as well as its low oxidation-reduction potential, under which the As was in reduced As(III) form. The first stage of the it removal process involves the oxidation of bivalent iron. removal of arsenic species from aqueous solutions. Epub 2014 Jul 9. A novel adsorbent, aluminum-loaded Shirasu-zeolite P1 (Al-SZP1), was prepared and employed for the adsorption and removal of arsenic(V) (As(V)) ion from aqueous system.
