Abstract

The H-point standard addition method (HPSAM)has been applied for simultaneous determination of maneb and zineb using1-(2-pyridylazo)-2- naphthol (PAN) as a reagent. Both maneb and zineb form winered colored complex with PAN at pH 9.2 which are soluble in Triton X-100. Zineband maneb can be determined simultaneously in the range of 0.414-3.446 μg mL-1and 0.663-3.316 μg mL-1respectively with satisfactory accuracy and precision.The proposed method has successfully been applied for the simultaneousdetermination of maneb and zineb in several synthetic samples, spiked watersamples and crops.
