求翻譯：The clear supernatant was decanted, 100ml isopropanol was added to the grey sludge, it was stirred for another hour, and the supernatant again decanted after the particle suspension had settled. The aluminum sludge at the bottom of the flask was now vacuum filtered through an inch of Celite in a buchner funnel and wash是什么意思？ 待解決
