摘要：
A method to analyze polymeric microcapsules of the herbicides alachlor and atrazine by reverse-phase high performance thin layer chromatography (RP-HPTLC) has been developed. The herbicidal concentration is determined by densitometry. The method is rapid and reproducible and offers a practical alternative to determination of alachlor and atrazine by elemental analyses. Impurities, metabolites, and decomposition products which may yield falsely high percentages of herbicidal content as determined by elemental analyses are readily detected by RP-HPTLC and are not sources of error.
