硫酸盐竹浆 ECF 漂白过程中糖类组分变化的研究

摘要: 应用高效液相色谱法研究了硫酸盐竹浆 ECF 漂白过程中二氧化氯漂白段糖类组分的变化情况。结果表明,葡聚糖、木聚糖和阿拉伯聚糖在二氧化氯漂白过程中有不同的降解率,葡聚糖降解率只有 0.133%,而木聚糖的降解率为 0.907%,阿拉伯聚糖的降解率达 79.77%,明显高于葡聚糖的降解率。

Abstract: In this paper, change of saccharide components in bamboo sulfate pulp during chlorine dioxide bleaching was studied by HPLC. The results showed that, glucosan, xylan and araban were degraded during chlorine dioxide bleaching. The loss of glucosan was 0.133 %. The degradation rate of xylan was 0.907 %. The degradation rate of araban reached 79.77%. The degradation rate of xylan and araban was higher than that of glucosan.
