壳聚糖植物栽培钵的制备与降解性研究

Preparation and degradation study of chitosan-plant-cultivation basin

研究了壳聚糖植物栽培钵(PCB)的制备方法,以及醋酸浓度、壳聚糖浓度和不同碱处理方式对壳聚糖PCB在土壤中降解的影响。结果表明,随着醋酸浓度的增加,壳聚糖PCB降解速度加快;壳聚糖浓度越高,PCB所需分解的时间越长,PCB有碱处理过的降解时间明显比无碱处理过的要长。同时,通过协方差分析,提出了醋酸浓度、壳聚糖浓度及不同碱处理方式对PCB降解率影响的模型。

The preparation of chitosan-plant-cultivation basin is reviewed. The effect of chitosan concentration, acetic acid concentration and whether plant cultivation basin treating with base will influence degradation of chitosan-plant-cultivation basin are studied. The results show that with acetic acid concentration increasing, the degradation rate of chitosan-plant-cultivation basin is improved; the higher the chitosan concentration, the longer degradation time of the chitosan- plant-cultivation basin is; the degradation time of chitosan-plant-basin treated with base is obviously longer than that without base. The model of the effect of chitosan concentration, acetic acid concentration and treating plant cultivation basin with base is proposed according to correspondence analysis.
