摘  要：
采用微波辐照氯化锌法,对以酸枣核壳为原料制备活性炭开展了工艺及性能研究。通过正交试验法研究了不同因素:氯化锌浓度(A)、浸渍时间(B)、微波功率(C)、辐照时间(D)对酸枣核壳活性炭的得率、碘吸附值、亚甲基蓝吸附值的影响。结果表明:微波辐照氯化锌法制备酸枣核壳活性炭的最佳制备工艺条件为A3B1C3D2,即氯化锌浓度50%,浸渍时间14 h,微波功率700 W,辐射时间7 min;在此条件下,酸枣核壳活性炭的得率为60%,碘吸附值与亚甲基蓝脱色力分别为933.24 mg/g和111.92 m L/g;不同处理量的梯度试验表明,该工艺具备大规模处理酸枣核壳的能力。

摘  要：
Taking the wild jujube kernel shell as raw material,process and properties of activated carbon by microwave irradiation with zinc chloride method was studied. The effects of different conditions such as zinc chloride concentration( A),dipping time( B),microwave power( C),and irradiation time( D) on the yield,iodine adsorption value and methylene blue adsorption value of the activated carbon made from jujube nuclear shell was also studied by an orthogonal experiment. The result showed that the optimum process conditions was A3B1C3D2,naemly the zinc chloride concentration 50 %,dipping time 14 h,microwave power 700 W,and radiation time7 min. Under this condition,the yield,iodine adsorption value and decolorizing capacity for methylene blue were60 %,933. 24 mg / g and 111. 92 m L / g respectively. Different gradient tests showed that this technology was able to process jujube nuclear shell in large scale.
