摘要
本文通过对氢离子选择电极（pH复合电极）的性能研究，拟定了用pH复合电极测定HCHO含量的有效方法，并通过对具体样品的分析和常规酸碱滴定法，间接碘量法比较，获得了满意的结果。
Through research on the characteristics of hydrogenion choice electrode (pH multiple electrod), this arti-cle recommends the effective means of measuring the content of formaldehyde by pH multiple electrod. By research on the sam-ples and comparing with acid-base titration and indirect iodimetric, satisfactory result can be obtained.
