Abstract

Herein, the application of granular activated carbon, jujube, and barberry tree stem powder for the removal of gasoline and kerosene from water was investigated. Kerosene removal rates upwards of 68.48, 83.87, and 99.02% were achieved using jujube tree stem powder, barberry tree stem powder, and granular activated carbon, respectively. Besides, gasoline removal rates upwards of 69.35, 55.02, and 95.59% were attained using jujube tree stem powder, barberry tree stem powder, and granular activated carbon, respectively. Isotherm data were further investigated and fitted using Langmuir, Freundlich, and Elovich models. The results indicated that the adsorption onto jujube adsorbent is a multilayer adsorption process over a heterogeneous surface, which is best illustrated by the Temkin (Ave. R²= 0.95) model. It was found that the Temkin isotherm (Ave. R²= 0.81) best describes the properties of barberry stem powder in the adsorption of gasoline and kerosene from water. Moreover, the best models to describe the characteristics of granular activated carbon in the adsorption of gasoline and kerosene from water were Freundlich (Ave. R²= 0.74) and Langmuir (Ave. R²= 0.73) isotherms, respectively. The adsorption kinetics showed that the pseudo-second-order was appropriate in modeling the adsorption kinetics of gasoline and kerosene to the studied adsorbents (R²>0.74).

红枣和杨梅干粉与市售活性炭吸附汽油和煤油的等温线和动力学研究。

本文研究了颗粒活性炭、红枣和杨梅干粉在水中脱除汽油和煤油中的应用。用红枣干粉、杨梅干粉和颗粒活性炭分别可达到68.48%、83.87%和99.02%以上的煤油去除率。枣树茎粉、杨梅茎粉和颗粒活性炭对汽油的去除率分别达到69.35%、55.2%和95.59%以上。使用Langmuir, Freundlich和Elovich模型进一步研究和拟合等温线数据。结果表明，红枣吸附剂上的吸附是在非均质表面上的多层吸附过程，Temkin (Ave. R2= 0.95)模型最能说明这一点。结果表明，Temkin等温线(Ave. R2= 0.81)最能描述小檗干粉对水中汽油和煤油的吸附性能。此外，描述颗粒活性炭吸附水中汽油和煤油特性的最佳模型分别是Freundlich (R2= 0.74)和Langmuir (R2= 0.73)等温线。吸附动力学结果表明，汽油和煤油对吸附剂的吸附动力学符合准二级模型(R2>0.74)。

期刊介绍： The International Journal of Phytoremediation (IJP) is the first journal devoted to the publication of laboratory and field research describing the use of plant systems to solve environmental problems by enabling the remediation of soil, water, and air quality and by restoring ecosystem services in managed landscapes. Traditional phytoremediation has largely focused on soil and groundwater clean-up of hazardous contaminants. Phytotechnology expands this umbrella to include many of the natural resource management challenges we face in cities, on farms, and other landscapes more integrated with daily public activities. Wetlands that treat wastewater, rain gardens that treat stormwater, poplar tree plantings that contain pollutants, urban tree canopies that treat air pollution, and specialized plants that treat decommissioned mine sites are just a few examples of phytotechnologies.
