摘要：Inorganic mercury (HgCl2) in activated sludge, sewage, urine, and aqueous extract of feces was alkylated under irradiation. A considerable amount of alkylmercury was formed by irradiation of inorganic mercury solution containing acetic acid or propionic acid in the presence of ammonia but only a small amount of alkylmercury formed in the absence of ammonia. This fact suggests that aminomercuric chloride (HgNH2Cl), formed by the reaction of mercuric chloride with ammonia, accelerated the photochemical alkylation of inorganic mercury. It was also found that creatinine, which was contained in sewage and urine, showed a photochemical alkylating ability but creatine, the open form of lactam ring of creatinine, did not show such ability.
