摘要

为探究改性前后生物质炭的理化属性变化及其对邻苯二甲酸二乙酯（DEP）的吸附机理，以椰子壳和花生壳为原料制备生物质炭，分别进行14% H3PO4改性和1.0 mol/L NaOH-30% H2O2联合改性处理。结果表明：改性后生物质炭的芳香化程度和含氧官能团含量增加，除C300N （经NaOH-H2O2改性的300℃—椰子壳生物质炭）外比表面积（SA）都增大。P800N （经NaOH-H2O2改性的800℃—花生壳生物质炭）有最大的SA （584.22 m2/g），因此对DEP的吸附亲和力最高。经过NaOH-H2O2联合改性的生物质炭对DEP的有机碳标化分配系数Koc（Ce=0.1Sw）值较高，对DEP的吸附亲和力更强。π-π EDA相互作用在所有生物质炭对DEP的吸附过程中发挥了重要的作用，而孔隙填充效应主导了原始生物质炭、经NaOH-H2O2改性的生物质炭和经H3PO4改性的800℃-生物质炭对DEP的吸附。与原始生物质炭相比，由氢键形成的水团簇作用抑制了经H3PO4改性的300，500℃制备的生物质炭对DEP的吸附。此外，氢键作用有助于增强低温（300℃）生物质炭对DEP的吸附亲和力。

Abstract

In this study

biochar were produced from coconut shell and peanut shell

and then modified with 14% H3PO4 and 1.0 mol/L NaOH-30% H2O2

respectively. The changes of physicochemical properties of biochar before and after modification and the sorption mechanism of diethyl phthalate (DEP) were studied. The results showed that the aromatization degree and the content of oxygen-containing functional groups of modified biochar increased

the specific surface area (SA) increased except C300N (the 300℃-coconut shell biochar modified by NaOH-H2O2). P800N (the 800℃-peanut shell biochar modified by NaOH-H2O2) had the highest sorption affinity for DEP because of the largest SA (584.22 m2/g). The sorption affinity of DEP by the NaOH-H2O2 modified biochar was stronger because of the higher organic carbon partition coefficient Koc (Ce=0.1Sw) value. The π-π EDA interaction played an important role in the sorption of DEP by all biochar

while the pore-filling effect regulated the sorption of DEP by the original biochar

NaOH-H2O2 modified biochar and H3PO4 modified 800℃-biochar. The water clusters formed by hydrogen bonding inhibited the sorption of DEP by the 300℃- and 500℃-biochar modified by H3PO4 compared with the original biochar. In addition

the hydrogen bonding was helpful to enhance the sorption affinity of low-temperature (300℃) biochar for DEP.
