This paper discusses the strategies and practices for controlling the hexavalent chromium content of leather,through improving tanning technology,optimizing tanning process parameters,including precise control of pH,temperature and tanning time and other measures,as well as using high-precision testing equipment to screen raw materials rigorously to control the hexavalent chromium content.Finally,this paper takes a tanning enterprise as an example to rationally design and apply these technological solutions,and the test results show that these technological solutions perform well in reducing the content of hexavalent chromium,and the environmental protection and quality control of the production process have been significantly improved.This study aims to provide reliable technical support for green manufacturing in the tanning industry and promote the sustainable development of the industry.
