Synthesis of adsorbed materials from Bentonite Co Dinh – Thanh Hoa, Application for removal of ammonium in water treatment
Abstract
Adsorber was purified synthesized from Co Dinh Bentonite ore, Thanh Hoa by ultrasound vibration method combines deposition, then be modified with the Fe3+ to improve quality and increase the adsorption capacity of ammonium domestic processing. The effect of ultrasonic vibration time, centrifugal velocity and Fe3+ ion denitration ratio were investigated. Characteristic properties of the material were determined by IR, EDX, IR spectroscopy, etc. The specific surface area and adsorption properties of the material were evaluated using the BET method. The maximum adsorption capacity for ammonium in the water is 40.65 (mg / g).
