This manuscript describes the adaptation of Sequential Injection Analysis (SIA) for the determination of silica, iron, ammonia, and phosphates, in water as a routine method being used by the quality control unit of a Petrochemical industry in Saudi Arabia (Ibn Zahr). The results obtained from the adopted SIA methods were found to be in agreement with results obtained from batch spectrophotometric APHA Standard methods (American Public Health Association).SIA has the additional advantage of reducing cost by minimizing time, amount of reagent consumed, man power required and improved accuracy of analysis due to computer aided analysis procedure.
