【摘要】：采用限氧升温法在不同的炭化温度和时间下制备4种花生壳生物炭,考察其对土壤吸附邻苯二甲酸二甲酯(Dimethyl phthalate,DMP)的影响。结果表明,添加生物炭能显著提高土壤对DMP的吸附能力。Langmuir模型和Freundlich模型均能较好的拟合添加生物炭土壤对DMP的吸附,相关系数分别介于0.90~1.00和0.95~0.99之间。随着生物炭添加量的增加,土壤对DMP的吸附能力明显增强且非线性特征更加突出;在生物炭高添加量条件下,炭化温度高且炭化时间长的生物炭对土壤吸附能力的增强作用更为显著。在Ce=0.001 Sw和Ce=0.01 Sw条件下,生物炭对土壤吸附DMP的贡献率分别介于80.80%~98.58%和67.30%~96.37%之间,表明生物炭对土壤吸附DMP发挥着主导作用。
[Abstract]:The limited oxygen temperature method in different carbonization temperature and time to prepare 4 kinds of peanut shell biochar, the study on adsorption of phthalate two formic acid methyl ester (Dimethyl two phthalate, DMP) effect. The results showed that biochar can significantly improve the fitting adsorption ability of.Langmuir model and Freundlich model of soil DMP can add to the DMP adsorption of biochar soil, the ranges of correlation coefficients were 0.90~1.00 and 0.95~0.99. With the increasing of the amount of biochar, the adsorption capability of soil DMP significantly enhanced and nonlinear features more prominent; in biochar high dosage conditions, enhancement of biomass carbonization high temperature and carbonization time long the adsorption capacity of soil was more significant. In the Ce=0.001 Sw and Ce=0.01 Sw under the condition of biochar on soil adsorption contribution rate of DMP between 80.80%~98.58% and 67.30%~96.37% respectively, showed that students Material charcoal plays a leading role in soil adsorption of DMP.
