三氯乙醛是许多化工产品、药品和农药的合成原料,是化学工业的一种重要中间体,而对农作物十分有害.近几年来,我省郑州、商丘、洛阳、偃师、孟津等地接连发生大面积农田受其危害的事件,造成减产或绝收,日趋严重.据报导,三氯乙醛在植物生理学上被称作生长紊乱剂,它能破坏植物细胞原生质的极性结构和分化作用,使细胞和核分裂紊乱,形成畸形病态组织,阻碍正常发育.目前,在测定污水、土壤和磷肥中三氯乙醛的方法研究较多,但对植株中三氯乙醛的测定方法,国内尚未见有报导.根据我们近两年的试验,利用乙醇提取,石油醚反提取,浓硫酸净化,比色测定
Chloral is a synthetic raw material for many chemical products, medicines and pesticides and is an important intermediate in the chemical industry, which is very harmful to crops. In recent years, chongqing, Shangqiu, Luoyang, Yanshi and Mengjin provinces It has been reported that trichloroacetal is reported to be a plant growth hormone disruptor in plant physiology that disrupts the polar structure and differentiation of plant cell protoplasts , So that the cells and mitotic disorders, the formation of deformed morulae, hinder the normal development.Currently, in the determination of sewage, soil and phosphate fertilizer in the study of chloral, but the determination of chlorhexidine in plants, the country has not yet See reports.According to our two years of experiments, the use of ethanol extraction, petroleum ether anti-extraction, concentrated sulfuric acid purification, colorimetric determination
