摘要: Abstract A new and optimized HPLC-ICPMS/MS method for the simultaneous determination of five most common phosphorous environmental pollutants in various water matrices has been developed, including aminomethylphosphonic acid (AMPA), glufosinate, glyphosate, fosamine, ethephon. We show that ICPMS/MS confers an average 20-fold improvement detection limit (0.1–0.3 µg P L−1) relative to comparable methods based on single quadrupole ICPMS detection, without incorporation any sample purification or preconcentration step. The was validated by determining intra-day repeatability (
