Abstract

The invention relates to a detergent, and in particular relates to a detergent for a cadmium-polluted building waste. The detergent is prepared from the following raw materials: dimethoxyacetic acid methyl ester, 1-(5-bicyclo[2.2.1]heptyl-2-alkenyl)-1-phenyl-3-(1-piperidyl)propyl-1-alcohol, ethyl 3-methyl-3-phenyl glycidate, meso-2,3-Dibromosuccinic acid, bis(2,4-dicumylphenyl)pentaerythritol diphosphite, and 2-diethyaminoethyl3-amino-4-propoxy-benzoate hydrochloride. The detergent for the cadmium-polluted building waste can directly wash the building waste, and has the removing effect of more than 96% to cadmium elements in the cadmium-polluted building waste; and the cleaning efficiency is high, the removing effect is good, and the detergent is suitable for being widely popularized and applied in the cadmium-polluted building waste environmental protection field.

Description

technical field [0001] The invention relates to a detergent, in particular to a detergent for construction waste polluted by cadmium. Background technique [0002] Cadmium is a non-essential element for the human body. It often exists in the form of compounds in nature, and its content is generally very low. Under normal environmental conditions, it will not affect human health. Cadmium is widely used in electroplating industry, chemical industry, electronics industry and nuclear industry and other fields. [0003] Cadmium is an important industrial and environmental pollutant, which mainly comes from the smelting of zinc, copper, and lead ores, and the industrial production of electroplating, batteries, alloys, paints, and plastics. The main source of cadmium pollution for occupational groups is inhalation, and the main source of cadmium pollution for non-occupational groups is food and inhalation. Cadmium is a non-essential and toxic element for the human body, and...
