Portable spectrophotometer was studied in the determination of hydrazine hydrate in sudden environmental pollution accident. Selecting ZZW-Ⅱportable spectrophotometer,we tested the performance indexes of instrumental method and determinating the arsenic in actual water samples. The experimental results showed that the detection limit of ZZW-Ⅱportable spectrophotometer was 0.04 mg/L,the determination lower limit 0.16 mg/L,the recoveries 84%-90%,and relative standard deviation 0-6.2%. The operation of ZZW-Ⅱportable spectrophotometer is simple and quick,which is suitable for sudden environmental pollution acciden of hydrazine hydrate in water.
