摘要
为了加快珍珠的漂白过程,探索了采用四乙酰乙二胺(TAED)作为漂白的活化剂。研究结果表明,TAED对珍珠的漂白具有催化漂白效果,可能是TAED与HOO-反应生成乙酸根负离子和二乙酰乙二胺(DAED),反应生成的过乙酸具有比H2O2更强的漂白能力所致,TAED浓度对珍珠表面质量有显著影响。
In order to speed up the process of pearl bleaching,a method that used Tetra Acetyl Ethylene Diamine（TAED） as the bleaching activator during the pearl bleaching was explored.The results of the study showed that TAED had a great effect on catalyzing pearl bleaching.It was due to the reaction between TAED and HOO-to generate the diacetyl ethylene diamine（DAED） and acetic root anion which had more strong blanching ability than H2O2.Besides,different concentrations of TAED had observation effects on surface condition of pearl.
