摘　　要：对纺织品禁用偶氮染料检测中所用的硅藻土进行研究，检测所用的硅藻土微观形貌以圆盘形为主，含有少量的筒形结构。硅藻土pH值和含水率对禁用偶氮染料回收率有一定影响，pH值在10．0～12．0，含水率控制在3％以内，符合检测要求。The diatomite used in detection of banned azo dyes in textiles is studied. SEM micrographs show that the diatomite features plate-form containing a small amount of tubular structure. The pH value and water content of diatomite have certain influence on the recovery rate of banned azo dyes. To meet the requirement of testing, the pH value should be controlled within 12-10, the moisture content is less than 3%.
