Simultaneous detection of carbaryl and atrazine in water by HPLC

Objective: To establish a method to examine carbaryl and atrazine in drinking water by HPLC at same time.Methods:The examined sample was chosen by dichloromethane and rotary vapoured to almost dry,use methylalcohol solute it,use to set dosage,use methylalochol and water as fluent,detected by photodiode array detector,the speed of fluent was 1.0 m per minute.Results:The least limit of detection was 0.05 mg per litre and 0.15 mg per litre each one.In the scope of add standard solution from 10 mg to 30 mg,the rate of recovery was from 90.8% to 99.7%,the RSD from 0.72% to 1.20%.Conclusion:The method of examining carbaryl and atrazine in drinking water by HPLC has the accuracy in determining its speciality.The operation is fast.Its result is precise and believable.
