零价铁掺杂氮化碳吸附水中卡马西平性能研究
Study on the adsorption of carbamazepine by zero valent iron doped carbon nitride in water
摘要
Abstract
Zero valent iron doped carbon nitride(Fe@N/C)was synthesized to address the shortcomings of insufficient adsorption performance and poor solid-liquid separation performance of traditional carbon materials.Compared to carbon nitride(N/C),Fe@N/C had a higher BET surface area,pore volume and pore size,facilitating the exposure of N-and O-contained active sites,as well as the adsorption of pollutants.Carbamazepine(CBZ)was selected as the target pollutant,and the effect of solution pH,adsorption time and pollutant concentration on the adsorption performance of Fe@N/C was studied in detail.The results indicated that CBZ could be adsorbed onto Fe@N/C in a wide pH range.The adsorption process conformed to the pseudo-second order kinetic model and Langmuir isothermal model.The maximum adsorption capacity of Fe@N/C obtained by fitting with Langmuir isothermal model reached to 56.88 mg/g.Fe@N/C exhibited good reusability,and the adsorbent can be quickly separated from water using a magnet after adsorption.The adsorption mechanism indicated that CBZ was adsorbed onto Fe@N/C through π-π electron donor acceptor interactions and hydrogen bonding.关键词
