以啤酒糟为原料,聚乙烯亚胺( PEI)为改性剂,戊二醛为交联剂,通过正交试验设计,采用矩阵分析法确立权重,进行改性工艺参数的优化,得到吸附率较高、吸附量较大、解吸率较高的高效生物吸附剂。分析结果显示,最优方案为4%PEI,1.5%戊二醛,交联时间0.5 h。各因素对正交试验的指标值影响的主次顺序为： PEI浓度>交联时间>戊二醛浓度。矩阵分析法能很好地解决啤酒糟吸附剂改性等多指标正交试验设计中最优方案的选择问题。

Using brewer’s grains as raw material, polyethylene imine ( PEI) as modification agent, glutaraldehyde as crosslinking agent, through the orthogonal experimental design, analysis method for determining weights by using the matrix was studied, the modification process parameters was optimized, obtained novel biosorbents of the higher adsorption rate got higher adsorption and higher desorption rate. Analysis results showed that the optimal scheme was the 4%PEI, 1. 5% glutaraldehyde, cross-linking time 0. 5 h. The important order of the factors influences on the tests index values can be determined:PEI concentration>crosslinking time>concentration of glutaraldehyde. Matrix analysis method can well solve the problem of optimal scheme of multi index orthogonal test design of brewer’s grains modification process.
