【摘要】 ①目的对铬天青S分光光度法测定饮用水中铝(简称CAS法)与水杨基荧光酮—氯代十六烷基吡啶分光光度法(简称SAF法)进行比较。②方法对两种方法基本情况以及准确度、精密度、干扰情况进行对比试验。③结果CAS法与SAF法相对标准偏差范围分别在4.6%～4.7%及1.8%～6.6%。④结论精密度方面,CAS法优于与SAF法;在除干扰方面方面,SFA法优于与CAS法。更多还原

【Abstract】 Objective To compare the advantage and disadvantages of CAS woth FAS method in detecting aluminium in drinking water.Method The accurate degree,exact degree and the interference of the two methods were examined.Results The relative standard variation was 4.6%~4.7% in CAS,and 1.8%~6.6% in FAS. Conclusion The exact degree of CAS is better than FAS.SAF is better than CAS in eliminating inferference.更多还原
