The removal of Bisphenol A in river water can be accomplished with the application of ozone. Ozone is widely used to disinfect drinking water due to its strong oxidizing properties. This study was conducted to investigate the removal of Bisphenol A in different areas of Skudai River. Batch experiments were conducted at initial Bisphenol A concentration of 0.5 mg L-1. The concentrations of Bisphenol A and dissolved ozone were measured using Ultra High Performance Liquid Chromatography (UHPLC) and UV-Visible spectrophotometer respectively. Based on the results obtained the stability of ozone in the water were very fast. Ozonewas quickly decomposed in water samples. The results indicated that the depletion of ozone varied from different dissolved organic carbon (DOC) value of water samples. Concentration of dissolved ozone was reducing rapidly after spiked into high DOC value (9.17 mg L-1) of river water. The results of the study have shown that ozonation could be used to effectively remove the Bisphenol A from water. The ozone depletions in river water at 120 seconds were about 87%-99%.

Background: Bisphenol A is characterized as an endocrine disruptor as it interferes with the synthesis of hormones and metabolism resulting in abnormality in the homeostatis of exposed persons. It is used in the production of polycarbonate and epoxy resins which are utilized in the preparation of almost all plastic packaging materials like plastic bottles, cans, food containers, and coating on food containers. Objective: To detect leaching of Bisphenol A in 15 samples of Bottled water and Beverages using High Performance Liquid Chromatography. Methods: Liquid-liquid extraction technique was used for analytical detection of BPA from bottled drinking water and beverages. Results: BPA contamination in Bottled drinking water was calculated through mean concentration for a time period of 30 days as (0.38 ng/ml - 0 day), 8.86 ng/ml (5th day), 17.85 ng/ml (10th day), 30.35 ng/ml (20th day) and 44.48 ng/ml (30th day)). The mean concentration of BPA was observed to be 0.25 to 2.25 ng/ml. Also, the mean concentration of BPA at different temperatures was observed to be 5.96 ng/ml (at 40C), 5.62 ng/ml (at 200C) and 8.80 ng/ml (at 550C). The above results revealed presence of high concentration of BPA in all the samples of bottled drinking water and beverages. Conclusion: The results obtained in the above study depicted considerable amount of BPA leaching from bottled containers into drinking water and beverages. Prolong usage of bottled water and beverages should be avoided to reduce the risk of human exposure to BPA through leaching. Also, it was found that high temperatures resulted in increased BPA leaching.

Solvent extraction used routinely for the preconcentration of carbamate herbicides from drinking water was replaced by sorption on the solid sorbent Separcol SI C18 T. Various factors of the preconcentration step that can affect the results of analysis were examined. Real drinking water samples contaminated by phenmedipham were analyzed by RP-HPLC in optimized conditions.
