真空過濾

VacuumFiltration實驗目的了解真空過濾之構造及其批次操作方法。以布式漏斗做恒壓過濾實驗，以決定實驗式。研討濾餅之比阻與過濾介質之阻力隨過濾壓力之變化。實驗理論布式漏斗轉接頭真空壓力計真空抽氣機取2張12.5cm的濾紙置入布式漏斗中以10mL的水潤濕。實驗步驟打開真空抽氣機，利用控制閥門調整至所欲之真空度(100mm-Hg)後，關閉真空室閥門。實驗步驟

從濾液體積為25mL開始記錄(t1)，每收集25mL記錄其時間(t)，直到濾液體積至225mL為止。實驗步驟225mL25mL清洗漏斗，倒出廢液後，增加真空度至200mm-Hg及400mm-Hg後重複上述步驟。不鎖緊真空室，即真空度為零的狀態下，重複上述步驟，記錄收集到濾液體積對時間之關係。增加泥漿之固含量至4%及6%，以真空度為200mm-Hg重複上述步驟。實驗步驟實驗數據Kaolinite(g)555.02510.0515.05H2O(mL)250.61250.43251.13250.54250.35252.13
