摘　　要：以次氯酸钠和氯化铵作为原料制备氯胺消毒剂,使用DPD分光光度法测量,研究pH、N∶Cl、反应时间和反应温度系列影响条件对氯胺消毒剂形态分布的影响。结果显示,氯胺形态组成和浓度水平受到反应条件N∶Cl和pH的影响较大。碱性条件下氯胺以一氯胺的形态存在;二氯胺在酸性和高N∶Cl条件下为主要产物;仅在酸性环境,过量游离氯存在的情况下,会有少量三氯胺的存在。存在形态对反应温度的变化不敏感。Sodium hypochlorite and ammonium chloride were used as raw materials to prepare chloramine disinfectant.DPD spectrophotometry was used to measure the influence of pH,N∶Cl,reaction time and reaction temperature on the morphology distribution of chloramine disinfectant.The results showed that the morphology and concentration of chloramine were greatly affected by the reaction conditions N∶Cl and pH.Chloramine exists in the form of monochloramine under alkaline condition.Dichloramine is the main product in acidic and high N∶Cl condition.Small amounts of trichloramine are present only in acidic environments where excess free chlorine is present.The existing form is insensitive to changes in reaction temperature.
