摘要
为提高农业废弃物资源化、高值化利用,缓解工业污染、守护水资源,以油茶籽壳为原料,经酸水解后获得油茶籽壳纤维素,利用环氧氯丙烷、二乙烯三胺进行改性制备复合材料,以甲基橙吸附率为指标采用Box-Behnken响应曲面试验法优化油茶籽壳纤维素复合材料的制备工艺。结果表明:油茶壳纤维素复合材料吸附剂的最佳工艺为环氧氯丙烷用量2.85mL,二乙烯三胺用量2.56mL,反应温度51℃,对甲基橙的吸附可达89.53%,有效增强了油茶籽壳纤维复合材料对甲基橙的吸附效果。提升油茶籽壳利用价值的同时可应用于水资源保护,实现废弃物的绿色循环利用。
To improve the resource utilization and high-value utilization of agricultural waste,alleviate industrial pollution,and protect water resources,this study used camellia seed shell as raw material to obtain camellia seed shell cellulose after acid hydrolysis,and modified with epichlorohydrin and diethylenetriamine to prepare composite materials.The Box-Behnken response surface test method was used to optimize the preparation process of camellia seed shell cellulose composite materials,with the adsorption rate of methyl orange as evaluation criterion.The results showed that the optimal preparing conditions for camellia seed shell cellulose composite adsorbent were:epichlorohydrin dosage of 2.85mL,diethylenetriamine dosage of 2.56mL,and reaction temperature of 51℃,achieving an adsorption rate of 89.53%for methyl orange and effectively enhancing the adsorption effect of camellia seed shell fiber composite material for methyl orange.Improving the utilization value of camellia seed shell can also be applied to water resource protection,realizing the green recycling of waste.
