| 摘 要： | 本文运用评价化学品对藻类毒的标准方法，得出邻苯二甲酸二甲酯对蛋白核小球藻的９６ｈ ＥＣ５０为３１３ｍｇ／ｌ。实验结果表明，蛋白核小球藻对邻苯二甲酸二甲酯有明显的富集与降解作用，富集量２４ｈ最大达１５．３６ｍｇ／ｇ，此后随时间的延长而逐步降低。５ｄ降解率为６６．８％。在对实验结果分析的基础上，提出了蛋白核小球藻对邻苯二甲酸二甲酯的二级降解反应动力学方程为－ｄｃ／ｄｔ＝ＫＮｒ，用此方程计算邻苯二甲酸二

| Abstract: | The standard method of algal bioassay for evaluating toxicity of toxic chemicals was applied and the 96h-EC50 of dimethyl phthalate (DMP) on inhibition the growth of chlorella pyrenoidosa was calculated as 313mg/l.It was found that chlorella pyrenoidosa has an ability of accumulating and biodegr-adating DMP. The algal accumulation reached maximum(15.36mg/g) at 24h, and declined gradually as time went on afterward. The biodegradation ratio of 5 days was 66.8%.On the basis of analysis of experimental result, a second -order kinetics equation of algal biodegradation was established (- dc/dt = KNr) .The average relative deviation between calculated values and observed values was 1.64% by using this equation. |
