基于SPSS多元线性回归分析不同因素对贮藏期间AES中二噁烷含量的影响

doi:10.3969/j.issn.1001-1803.2019.10.003

Abstract

Abstract:

Based on the results obtained from single factor experiments and in combination with multiple linear regressions, the influences of different factors on the content of dioxane in sodium fatty alcohol ether sulphate（AES）were investigated. The results show that the dioxane content in AES is positively correlated with EO number, temperature, pH and time during storage, i.e., more dioxane exists in the case of larger EO number, higher temperature, higher pH or longer time. According to the analysis with multiple linear regression, the contributions of the 4 factors to the increase of dioxane in AES are ranked as follows: EO number>pH>time>temperature. Sunshine has a slight influence on the increase of dioxane content.

Key words: sodium fatty alcohol ether sulphate, dioxane, multiple linear regression
