This paper reports the effects of initial urea concentrations and pH values on the performance of a capillary hemodialyzer for the removal of free ammonia (NH3) formed by enzymatic hydrolysis of urea. Air was chosen as the gas phase. NaOH was used for alkalinization of dialysate. It was shown that one of the most important parameters was free ammonia concentration. The degrees of alkalinization and the initial urea concentration, were also important. Although even without the addition of NaOH, about 42% of the initial urea can be removed in one hour.
本文报道了初始尿素浓度和pH值对用于去除由尿素酶水解形成的游离氨（NH₃）的毛细管血液透析器性能的影响。选择空气作为气相。使用NaOH对透析液进行碱化。结果表明，最重要的参数之一是游离氨浓度。碱化程度和初始尿素浓度也很重要。尽管即使不添加NaOH，一小时内仍可去除约42%的初始尿素。
