将商业化D151树脂用2mol/L的NaOH溶液淋洗转化为大孔聚丙烯酸钠树脂(简写为PNaA树脂),测定了PNa A树脂对黄连中生物碱的吸附性能。实验表明,PNaA树脂对黄连中生物碱的吸附量明显大于商业化D151树脂、D001树脂、XAD-4树脂、H103树脂、X-5树脂及AB-8树脂对黄连中生物碱的吸附量。黄连水溶液中p H值在4.5~8.7时,PNaA树脂对黄连中生物碱的平衡吸附量最大。随着黄连水溶液中离子强度的增加或温度的降低,PNaA树脂对黄连中生物碱的平衡吸附量减小。80%C_(2)H_(5)OH-0.3%NaCl混合溶液对PNaA树脂吸附黄连中生物碱的静态解吸率为100%。PNaA树脂可吸附生物碱浓度为0.625mg/mL的黄连溶液56.7BV(床体积),用5....

Macroporous sodium polyacrylate resin (denoted PNaA) was transformed from commercial D151 resin by leaching with 2mol/L NaOH. The adsorption properties of alkaloids in Coptis chinensis by PNaA resin were investigated. The experiment showed that the adsorption capacity of alkaloids in Coptis chinensis by PNaA resin was obviously higher than that of commercial D151 resin, D001 resin, XAD-4 resin, H103 resin, X-5 resin and AB-8 resin. The maximum adsorption capacity of alkaloids by PNaA resin was observed at the solution pH in the range 4.5~8.7. T...
