%X The condition for reaction of hydrazine with dimethylaminobenzaldehyde and the composition of complex formed in the presence of acid have been studied.The concentration of the complex is in proportion to the colour in a range of 1.00-0.002mg/L.The maximum absorbance is at 458um. The relative standard deviations with in the labs are 3.7%,0.9% and 0. 6% at 0.100, 0. 500 and 0.800mg/ L, respectively;and those among different labs are 4. 4%,1.3% and 0. 9%,respectively.The recoveries are 88% to 110%.
