Abstract

The present invention provides a treatment method of an arsenic removal material. The method comprises the following steps of performing reducer treatment on the arsenic removal material, and optionally performing ultrasonic treatment and / or alcohol stabilizer treatment on the arsenic removal material. The present invention also provides the treated arsenic removal material obtained with the method and an application of the arsenic removal material. The present invention also provides a method for performing arsenic removal treatment on a substance to be subjected to arsenic removal, and an arsenic removal product prepared with the method and an application of the arsenic removal product.

Description

technical field [0001] This application relates to the fields of chemistry and food, specifically, this application provides a treatment method for de-arsenic material and the processed de-arsenic material and its use; A method for arsenic treatment, and arsenic-depleted products prepared by the method and uses thereof. Background technique [0002] Since most arsenic compounds are toxic, and the raw materials used in production often have the problem of excessive arsenic, it is necessary to remove arsenic from the raw materials. After effective treatment of suitable arsenic removal materials, a better arsenic removal effect can be achieved, thereby achieving greater economic benefits. [0003] Rice bran is a by-product of rice processing. At present, my country produces about 10 million tons of rice bran every year. In addition to rich nutrients such as protein, fat, sugar, dietary fiber and minerals, rice bran also contains nutrients such as vitamin B, vitamin E, β-carot...
