Method for degrading methylene blue solution

Abstract

The invention discloses a method for degrading a methylene blue solution. According to the method, CuO is used as a catalyst for catalyze the decomposition of hydrogen peroxide to the methylene blue solution. As an effective catalyst, copper oxide can degrade sewage containing the methylene blue solution in a relatively short time. Furthermore, CuO is a nano-structured CuO membrane which has a large specific surface area and relatively strong base adhesion force and is capable of effectively catalyzing the decomposition of hydrogen peroxide to the methylene blue solution and effectively decoloring the methylene blue solution within 0.5 hour, and 100% degradation efficiency can be achieved within 4 hours; furthermore, the CuO membrane has very high stability and can be repeatedly used.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a method for degrading methylene blue solution. Background technique [0002] Today, harmonious coexistence between man and nature has been put on the agenda. While the economy is developing rapidly, many countries are facing different degrees of environmental problems. Water pollution is a challenge that people have to pay attention to. Industrial wastewater is a major source of water pollution. Methylene blue is a widely used organic dye. It is relatively difficult to degrade, has toxicity, and is relatively harmful to the environment. Hydrogen peroxide (H2O2) is generally used in industry 2 o 2 ) to oxidize methylene blue (C 16 h 18 ClN 3 S) degrades it into a non-toxic and colorless substance, but faces the problem of low catalytic efficiency, so scientists have further explored in order to find a suitable catalyst to improve the oxidation efficiency of hydrogen ...
