Chloramines, oxidant compounds used in municipal drinking water as sanitizing agents, potentiate hemolytic anemia when present in dialysate. Thus far, the addition of ascorbic acid to the dialysate and the use of granular activated carbon (GAC) have been the only reliable, practical methods reported for removing chloramines. This is a report on the bench-scale testing of five kinds of GAC from three manufacturers. The performance of 100 g of each carbon was studied in a 2-in-diameter column through which feed-water containing approximately 1.5 mg/L chloramines flowed downward at an average volumetric rate of 140 ml/min. The carbons' experimental capacities for chloramines differed by as much as one order of magnitude. The experimental results were used to estimate the capacity of a 9-in-diameter, 45-in-tall column of the best carbon. These scale-up estimations indicate that this sorbent may safely last through 156 5-h dialyses.
氯胺是用于市政饮用水消毒的氧化化合物，当存在于透析液中时会加剧溶血性贫血。到目前为止，向透析液中添加抗坏血酸和使用颗粒活性炭（GAC）是报道的仅有的可靠且实用的去除氯胺的方法。这是一份关于对来自三个制造商的五种GAC进行实验室规模测试的报告。在直径为2英寸的柱中研究了每种100克碳的性能，含约1.5毫克/升氯胺的进水以140毫升/分钟的平均体积流速向下流动通过该柱。这些碳对氯胺的实验容量相差多达一个数量级。实验结果用于估算直径9英寸、高45英寸的最佳碳柱的容量。这些放大估算表明，这种吸附剂可能安全地持续用于156次5小时的透析。
