作者用328只BALB/C小鼠,测得EDTA铁钠、EDTA铁铵和铁氰化钾三种漂白液的LD_(50)分别是1. 327、0. 993和2. 254g/kg;组成漂白液的三个主要成分是11. 00%EDTA 铁钠、8. 00%EDTA 铁铵和17. 32%铁氰化钾。三者对BALB/C 小鼠24小时内致死率分别为90%、80%和40%;组织学检查表明,三种漂白液均有心、肝、肺、脾、肾等病理改变,但铁氰化钾漂白液病变程度较EDTA 铁钠和EDTA 铁铵漂白液轻。由此推征铁氰化钾漂白液的毒性明显小于EDTA 铁钠和EDTA 铁铵漂白液。
The authors used 328 BALB / C mice to measure the LD_ (50) of sodium iron EDTA, iron ammonium EDTA and potassium ferricyanide respectively, which were 1. 327, 0.993 and 2. 254 g / kg respectively. The composition The main three components of the bleaching solution is 11. 00% EDTA sodium iron, ammonium dialdehyde 800% EDTA and 17.32% potassium ferricyanide. The mortality rates of BALB / C mice within 24 hours were 90%, 80% and 40% respectively. Histological examination showed that all the three bleaching solutions had pathological changes of heart, liver, lung, spleen and kidney, Potassium bleaching fluid lesion degree than EDTA iron sodium and EDTA iron ammonium bleach solution light. This lead to potassium ferricyanide bleach toxicity was significantly less than EDTA iron sodium and EDTA iron ammonium bleach.
