【摘要】 本文主要用离子色谱法与改良硫酸钡比浊法对大气硫酸盐化速率进行分析。通过曲线分析,空白实验,加标回收率分析,证明两种方法有良好的线性与准确性;对5个不同点位的碱片分析并通过t检验法进行检验,说明两种方法无明显差异。更多还原

【Abstract】 In this paper,two methods for analyzing air sulphation rate were studied and compared. One was ion chromatography and the other was barium sulfate spectrophotometry. Verified by responsibility analysis, blank experiment test and recovery percentage of standard samples, the accuracy and linearity of the two methods were evaluated. In T-test and analysis of 5 places alkali pieces, no obvious difference between the two methods was found.更多还原
