- 中文摘要: This study describes a turbidimetric technique for determination of melamine in wastewater of petrochemical companies. A single reagent (bioxalate ions) is used and an insoluble ion-pair (melamine:bioxalate 1:3) produced. The reproducibility of the method is excellent and relative standard deviation for six repeated experiments is 1.5%. An interferences study was carried out, and it was found that the common species occurring in wastewater has no interference effect on the determination of melamine. The interference effect of Al3+ was eliminated by its precipitation as Al(OH)3 at pH 7. Finally this method was successfully used in the determination of melamine content of Urmia Petrochemical Company, a local melamine producer.
