A microwave aqueous synthesis method has been successfully utilized for preparing mesoporous carbon adsorbents, and the microwave aqueous treatment duration has been decreased from 10 h of hydrothermal treatment to less than 1 h. The mesoporous carbons have Brunauer–Emmett–Teller (BET) surface areas ranging from 1913.5 to 2213.8 m²/g, pore volumes from 1.41 to 2.40 cm³/g, average pore diameters between 3.29 and 4.40 nm, and the surfaces of the mesoporous carbons are mainly hydrophilic with few O-containing functional groups. The pore textural properties of the mesoporous carbons critically depend on the microwave treatment conditions. All the mesoporous carbons showed considerable adsorption ability for berberine hydrochloride and matrine, and the highest adsorption capacities at the initial concentration of 0.08 mg/mL and 298 K are 363.8 mg/g and 269.7 mg/g, respectively. Adsorption thermodynamic parameters of berberine hydrochloride and matrine on the selected carbon sample were calculated. The adsorption rate of the two alkaloids on the selected carbon sample is fast. These results indicate that the microwave-prepared mesoporous carbons could be promising adsorbents for highly efficient adsorption of berberine hydrochloride and matrine.

微波合成中孔碳高效吸附小ber碱和苦参碱。

微波水合成方法已经成功地用于制备中孔碳吸附剂，微波水处理时间从水热处理的10小时减少到不到1小时。介孔碳的Brunauer-Emmett-Teller（BET）表面积为1913.5至2213.8 m ² / g，孔体积为1.41至2.40 cm ³/ g，平均孔径在3.29和4.40 nm之间，介孔碳的表面主要是亲水的，几乎没有含O的官能团。介孔碳的孔结构性质主要取决于微波处理条件。所有的中孔碳均显示出对盐酸小ber碱和苦参碱的相当大的吸附能力，在初始浓度为0.08 mg / mL和298 K时，最高的吸附能力分别为363.8 mg / g和269.7 mg / g。计算了盐酸小ber碱和苦参碱在所选碳样品上的吸附热力学参数。两种生物碱在所选碳样品上的吸附速率很快。
