水热炭对废水中碱性染料吸附的研究现状

Research Status of Adsorption of Basic Dyes in Wastewater with Hydrochar

水热炭是一种新型的生物质炭,具有比表面积较大、表面官能团丰富、孔隙度较高、偏碱性、稳定性好等优点,被广泛应用于废水处理。本文对水热炭制备的影响因素,水热炭吸附水中碱性染料的影响因素、吸附等温线和吸附动力学等的研究进展进行了综述,并对水热炭应用于吸附碱性染料的未来研究方向进行了展望。

Hydrocharis was a new kind of biochar,which had large specific surface area,rich surface functional groups,high porosity,alkalinity,good chemical stability,etc.,therefore,it was widely used in wastewater treatment.In this paper,the influence factors of hydrochar preparation,the adsorption characteristics of basic dyes with hydrothermal carbon such as adsorption influence factors,isotherm and kinetics,were reviewed.The future research direction of hydrothermal carbon application for basic dyes was prospected.
