中文摘要：

以马尾松硫酸盐浆纸浆纤维素为原料,利用热溶胶转相法,在纤维素再生过程中将荆树皮栲胶包埋在纤维素基体上,制备出包埋型球形纤维素吸附剂ESCA,并考察其对盐酸小檗碱的吸附效果。结果表明,当荆树皮栲胶用量为1.00%,碳酸钙用量为6.67%,明胶用量为3.33%,油酸钠用量为0.50%时,制得的吸附剂ESCA的含水率为73.2%,比表面积为436.2m2/g,荆树皮栲胶的包埋率为98.26%。当盐酸小檗碱初始质量浓度为200mg/L,溶液pH值为7,吸附时间为3.0h,吸附温度为30℃时,ESCA对盐酸小檗碱的吸附率为95.28%,平衡吸附容量为23.82mg/g。

英文摘要：

The embedded spherical cellulose adsorbent（ESCA） was prepared by the thermal solution-gel transition technique using masson pine kraft pulp cellulose as materials,and the adsorption of berberine hydrochloride was studied.Black wattle extract was embedded in cellulose matrix in cellulose regeneration process.The results showed that,the embedded spherical cellulose adsorbent with 98.26% of encapsulation efficiency for black wattle extract could be obtained under the optimal conditions（1.00% of black wattle extract dosage,6.67% of calcium carbonate dosage,3.33% of gelatin dosage and 0.50% of sodium oleate dosage）.The moisture content of ESCA was 73.2%,and the specific surface area was 436.2m2/g.The adsorption percentage and the equilibrium adsorption capacity of berberine hydrochloride by ESCA could reach 95.28% and 23.82mg/g,respectively,under such conditions as 200mg/L of berberine hydrochloride concentration,4 of the solution pH,3.0h of the adsorption time and 30℃ of the adsorption temperature.
