Abstract

A hydrogen sulfide purification material and preparation method thereof; the purification material comprises a manganese oxide; the manganese oxide reacts with hydrogen sulfide to generate a pink manganese sulfide; and the color of the purification material changes from yellow-brown to pink. According to the color change of the material, the purification effect of the hydrogen sulfide and the usage saturation of the material can be determined. The preparation method of the hydrogen sulfide purification material comprises preparing a nanoscale hydrogen sulfide purification component, adding adjuvants therein for mixing and forming, and obtaining a granular material having a stable shape after stoving and calcining, thus being simple in operation, and being suitable for industrial production.

Description

technical field [0001] The invention relates to the field of environmental protection material preparation, in particular to a hydrogen sulfide purification material and a preparation method thereof, and relates to a preparation method of an efficient, high temperature resistant, reproducible and color-changing indicating type hydrogen sulfide purification material, which is suitable for industrial tail gas, manufacturing Removal of hydrogen sulfide gas produced in industrial production such as industry and sewage treatment. Background technique [0002] Hydrogen sulfide is one of the main pollutants in the atmosphere and is a highly irritating and highly toxic gas. Hydrogen sulfide gas is widely produced in oil exploration, coal mining industry, papermaking and leather, food processing and other industries, as well as sewer, sewage purification, feces and other operations. Hydrogen sulfide is an acute and highly toxic substance with a "rotten egg" smell. Concentrations of ...
