Abstract
An adsorbent for wastewater treatment includes titanium hexametaphosphate; the titanium hexametaphosphate is mainly prepared from hexametaphosphate and titanium salt. The adsorbent is an aggregate of micron or nanometer particles, with a large surface area and a good adsorption performance. The adsorbent, as a wastewater treatment agent, may effectively remove thallium contaminants in various water bodies such as underground water, surface water, chemical wastewater and mine wastewater at a removal rate of 99.8%; and the adsorbent has a good removal capability for heavy metals in water such as cadmium, plumbum, copper, stibium, cesium and uranium. The adsorbent has a wide applicable PH value range, and especially has a good adsorption capacity, stability and heat resistance under acidic conditions.
