Phosphorous was determined as phosphate using the vanadate phosphomolybdate UV-Visible Spectrophotometric (Shimadzu Corporation, Tokyo Japan, Model UV-3101PC) method where orthophosphate reacts with vanadate molybdate reagent to form a yellow-orange complex whose absorbance was measured at 420 nm [16].
