在０．３６ｍｏｌ／ＬＮＨ４Ｃｌ－０．０４ｍｏｌ／ＬＮＨ３Ｈ２Ｏ（ｐＨ８．３１）支持电解质中，溶菌酶（ＬＥ）产生一个极谱催化氢波，峰电位为－１．８０Ｖ（ｖｓ ＳＣＥ）．该极谱催化氢波二阶导数峰电流与ＬＥ浓度在 １．２ × １０－８－５．６ × １０－８ｍｏｌ／Ｌ范围内有线性关系．用于鸡蛋清中ＬＥ的测定，结果满意．
Lysozyme (LE) produced a polarographic catalytic hydrogen wave with a peak potential of -1.80V (vs SCE) in 0.36 mol / L NH4Cl-0.04 mol / L NH3H2O (pH 8.31) The second derivative peak current of this polarographic catalytic hydrogen wave has a linear relationship with LE concentration in the range of 1.2 × 10-8-5.6 × 10-8 mol / L. LE for the determination of egg white, the results are satisfactory.
