Determination of glufosinate-ammonium and malathion in residue oil from palm pressed fiber using high performance liquid chromatography

Determination of glufosinate-ammonium and malathion in residue oil from palm pressed fiber using high performance liquid chromatography

A study on the determination of organophosphorus pesticides (OPPs), namely glufosinate-ammonium and malathion in residue from palm pressed fiber (PPF). Three PPF samples were taken from three different areas, FELDA Lepar, FELDA Chini 1 and FELDA Chini 2.The extraction of oil residue in PPF was car...

Three PPF samples were taken from three different areas, FELDA Lepar, FELDA Chini 1 and FELDA Chini 2.The extraction of oil residue in PPF was carried out using supercritical fluid extraction (SFE), using supercritical carbon dioxide (CO2) at 3000 psi in isothermal in 60°C for 60 minutes.
