铬酸洗液是医院制剂室常用的玻璃溶器清洗剂,由于其中含有重铬醋钾(六价铬离子),故能呈现出铬的毒性。重铬酸钾为棕红色结晶,其水溶液氧化力较弱,在浓硫酸中才具有强烈的氧化作用,这是因为在化学反应中生成了重铬酸,它不稳定,能进一步反应生成铬酐,而表现出强力的去污作用。重铬酸和铬酐可使人发生中毒。制剂人员在使用铬酸洗液时,若不加以防护,可引起一系列的中毒症状。如上呼吸道粘膜水肿,咳嗽,鼻部刺激发生烧灼感,鼻粘膜充血而产生鼻塞、水样鼻液、喷嚏等急性卡他
Chromic acid lotion is commonly used in hospital preparation room glassware cleaning agent, which contains chromium dichromate (hexavalent chromium ions), it can present chromium toxicity. Potassium dichromate is a reddish-brown crystal, and its aqueous solution has a weak oxidizing power, which is strongly oxidized in concentrated sulfuric acid because of the formation of dichromic acid in a chemical reaction which is unstable and capable of further reaction to produce chromic anhydride , While showing a strong decontamination. Dichromic acid and chromic anhydride can cause poisoning. Formulation personnel in the use of chromic acid lotion, if not be protected, can cause a series of symptoms of poisoning. Such as respiratory mucosal edema, cough, nasal irritation burning sensation, nasal congestion caused by nasal congestion, watery nose fluid, sneezing and other acute kata
