Abstract
The new microfluidic analysis system use to determine the hydrazine based on the reaction between Spectrophotometric reagent vanillin with sulfuric acid and hydrazine
sulfate to form the hydrazone complex . Wavelength 410 nm , and give a linear range (7.685 x 10
-6 – 5.379 x 10-4) molar .The detection limit is 7.685 x 10-6 molar and the
regression coefficient R
2 value is 0.9979. Reproducibility, SD, RSD, dead volume and interferences have been calculated. The reaction time, concentration of reagent and
volume of sample has been optimized. The method has been successfully applied for the determination of hydrazine in water and pharmaceutical samples.
Key Words : Microfluidic analysis, Chip , Hydrazine , Vanillin , pharmaceutical samples.
