Abstract

The invention relates to a preparation technology for an arsenic removal material. The arsenic removal material is prepared from deionized water, ferric chloride, natural zeolite and a sodium hydroxide (NaOH) solution. During preparation, natural zeolite is adopted as the basis, and after the surface is loaded with ferric chloride, the natural zeolite-ferric chloride composite arsenic removal adsorption material is obtained, the obtained adsorption material is high in adsorption efficiency, high in alkali resistance and capable of achieving solid-liquid separation conveniently, and the material is high in adsorption material, high in alkali resistance, capable of achieving solid-liquid separation conveniently, low in cost, easy to obtain and easy to prepare and has the good application prospect.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering water treatment, and in particular relates to a preparation process of arsenic-removing material. Background technique [0002] Elemental arsenic is non-toxic to humans and organisms, but arsenic compounds are quite toxic. According to reports, about 110,000 tons of arsenic enter the hydrosphere every year in the world through various channels; because arsenic has a wide range of uses and is closely related to people's production and life, many industrial productions will produce a large amount of arsenic-containing waste water that exceeds the standard. Therefore, the removal of arsenic from wastewater in industrial production and drinking water in daily life is an important issue related to people's livelihood. [0003] At present, there are many methods for removing arsenic from wastewater, mainly including coagulation precipitation method, adsorption method, ion exchange met...
