                          果壳活性炭的水溶物的测定
                          C.2.1水,GBT682,三级
                          C.2.2定性滤纸,GBT1914,B等,中速(102)
                          C.3.1磨口三角烧瓶,250mL
                          C.3.2直管式回流冷凝管
                          C.3.3漏斗,直径为向0mm-125mm
                          C34蒸发皿,容量为100m
                          C.3.5分析天平,感量0.0001g
                          3.6电热恒温干燥箱0℃~300℃
                          C.3.7干燥器,内装无水氯化钙或变色硅胶
                          C.3.8电炉
                          C.3.9移液管,50m
                          C.3.10温度计,100℃
                          C.3.11烧杯,250ml
                          C.3.12量筒,100ml
                          C.3.13真空抽滤瓶,500mL

                          C.4试样及其制备
                          对所送果壳活性炭样品用四分法取出30g,置于150℃±5℃电热恒温干燥箱内,干燥2h后放入干燥器中
                          冷却至室温备用。

                          C.5果壳活性炭测定步骤
                          C.5.1称量10.00g±0.01g的试料,精确至0.0001g,置于250mL磨口三角烧瓶中
                          C.5.2取100.0mL±0.5mL沸水,用其中20mL润湿试料,用剩余部分水洗涤烧瓶四周。将烧瓶接
                          到直管式回流冷凝管上并置于电炉上,加热至微沸,保留15min,加热过程中应保证炭不溅到烧瓶
                          壁上
                          C.5.3取下磨口三角烧瓶,立即过滤(滤纸须先用水润湿),滤液收集在500mL真空抽滤瓶中并冷却
                          C.5.4将蒸发皿在150℃±5℃下预先干燥至恒量(两次称量相差不大于0.001g)
                          C.5.5用移液管吸取50mL滤液,转移至已称量的蒸发皿中。

                          C.5.6将蒸发皿置于95℃-100℃电热恒温干燥箱内,待滤液蒸发干燥后(蒸发过程避免煮沸以防残。
