CONCLUSION
The phosphate determination by molybdenum
blue method in conjugation with uv-visible
spectrophotometer is a simple method that can be
carried out in common laboratories.The method is
simple and cheap compare to other methods, because it
neither involves extraction of the analyte, nor requires
any sophisticated instruments like HPLC. The strict
control of pH is not necessay in this method. In addition,
the developed new method is working satisfactorily
for the determination of phosphate present in various
samples analyzed . The system obeys Lambert-Beer’s
