The relationship between the absorbance A580nm of the iodine-starch and the consistence of the starch is a straight line. The starch is degraded by a-amylase at 37C for 10 minute, and the degradation is stopped by adding CuCl2/HCl complex solution. The determination of a-amylase is measured by the absorbance of iodine-starch at 580am and the formula: R= (5/B)(1-Ax/As).

In this paper,the micro-amount determination of SO_4~(2-) is studied af- ter the exchange reaction between the SO_4~(2-) and BaCrO_4,an equvilent wei- ght of H_2Cr_2O_7 in acid medium is obtained and determined with blue light of iodized starch method indirectly by spectrophotometry.This method is rapid,sensitive,reprodueible,and Simpler than that of turbidimetry and other spectrophotometric methods. Beer's law is obeyed for the linear range 8—80 ug of SO_4~(2-) per 50ml. It is suitable for the determination of SO_4~(2-) in water and in other pure chemicals.From the elementary experiment evidence,it is also possible to determine the organic sulfides(COS,CS_2)in water gas,if the organic sulfides hydrolyze firstly and transfer the S~(2-) into SO_4~(2-)
