Description

technical field [0001] The invention relates to the technical field of photocatalyst preparation and application, in particular to a preparation method and application of a porous carbon composite material derived from a copper metal organic framework. Background technique [0002] Industrial dye wastewater is the main source of water pollution. Among them, triphenylmethane dyes are widely used as industrial dyes due to their bright color, high color fixation rate, and good color fastness. It is highly toxic, difficult to degrade and easy to cause cancer, so it has become one of the wastewater that needs to be treated urgently at this stage. As a derivative of triphenylmethane, methyl violet has good water solubility and is widely used in dyeing of silk, acrylic fiber, linen, paper, leather, pigments, printing inks and inks, etc. It is very toxic to organisms when it is directly discharged into water. Big. There are a variety of methods for the removal of organic dyes, inc...
