本文研究了测定铜电解液中氨基酸的新方法。根据试验结果，吸收波长选择λ＝570nm，当PH＝5．4时，氨基酸的在观摩尔吸光系数ε＝8．14×104，氨基酸的线性范围是0～12μg／10ml。用于铜电解液中氨基酸的测定，获得满意结果。
In this paper, a new method for the determination of amino acids in copper electrolyte has been studied. According to the experimental results, the absorption wavelength selection λ = 570nm, when PH = 5.4, the molar extinction coefficient of the amino acid ε = 8.14 × 104, amino acid linear range of 0 ~ 12μg / 10ml. For the determination of amino acids in copper electrolyte, satisfactory results were obtained.
