Zhang Guizhu, Wang Yuemei, Zhao Peng, He Xiwen and Shi Huiming (Department of Chemistry, Nankai University, Tianjin 300071, China) Lu Jixin (Department of Pharmacy, Tianjin Medical University, Tianjin 300203, China) [WT4”HZ〗  
Based on the reaction of cysteine and cobalt (Ⅱ) in NH 4Cl NH 4OH solution, a new spectrophotometric method for the determination of cysteine was developed. The molar absorptivity is 7.98×10 3 L·mol -1 ·cm -1 at 284 nm and the results met the Beer′s law in the range of 0~2.0×10 -4 mol·L -1 . The method was applied successfully in cysteine assay in urine.
