近年来由于生产上的需要,络合剂和螯合剂作为隐蔽剂的研究正在迅速发展,它们已广泛应用于分析化学、生物化学等学科的研究工作方面和工农业、国防工业、近代技术等部门的生产实践中。隐蔽剂在工业上最早是用于水的软化上,使水中碱土金属离子络合成为水溶性络合物而不复游离存在,以防止沉淀析出。但一般化学操作中亦经常需要
In recent years, research on complexing agents and chelating agents as camouflaging agents has been rapidly developed due to the needs of production. They have been widely used in the research work of analytical chemistry and biochemistry, as well as in the fields of industry and agriculture, national defense industry, modern technology and other departments Production practice. Concealment agent in the industry is the earliest for the softening of water, the water alkaline earth metal ions complexed to become water-soluble complexes and no longer exist free to prevent precipitation. However, it is often necessary in general chemical operations
