The impact of the total organic carbon (TOC), chlorine dosage, water temperature, reaction time, pH, and seasonal variation on the formation of haloacetic acids (HAAs) in the Karoon River in Iran was studied. The results showed that dichloroacetic acid and trichloroacetic acid were the most detected HAA5. The HAA5 formation potential (HAA5FP) levels in the Karoon River water in spring time, when the water TOC content exceeded 4 mg/L, were 1.38 times higher than during the winter season, when the water TOC content was below 3.5 mg/L. There was not a strong correlation between the HAA5FP and the residence time for the Karoon River water. For the range of the water temperatures studied, there was little variation in the HAA5FP in cold water, but in warmer water, the values of the HAA5FP varied quickly.
研究了总有机碳(TOC)、氯剂量、水温、反应时间、pH 值和季节性变化对伊朗卡伦河卤乙酸(HAAs)形成的影响。结果表明,二氯乙酸和三氯乙酸是检测到的最多的 HAA5。当水体 TOC 含量超过 4mg/L 时,春季水体 HAA5 形成潜力(HAA5FP)水平比冬季水体 TOC 含量低于 3.5mg/L 时高出 1.38 倍。HAA5FP 与卡伦河水的停留时间之间没有很强的相关性。对于所研究的水温范围,在冷水体中 HAA5FP 的变化很小,但在较温暖的水中,HAA5FP 的值变化很快。
