H‐Point Standard Addition Method for Simultaneous Determination of Maneb and Zineb

Parminder Kaur, Usha Gupta

Open full text 6 citations

Abstract

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