Abstract：

There　is　a　large　amount　of　strong　acid　wastewater　containing　fluorine　ion　generated　during　electrolytic　aluminum　foil　processing.　This　paper　will　investigate　the　EDTA　complexometry　fast　measuring　method　to　determine　the　aluminum　content　in　wastewater.　The　study　covers　the　impact　of　interfered　ions　on　aluminum　content　measurement,　acidity　selection,　and　the　determination　of　ending　point.　Using　standard　addition　method　and　multiple　measurements　on　samples,　it　demonstrates　that　the　EDTA　complexometry　method　satisfies　the　requirements　in　precision　and　accuracy.　The　aluminum　recoveries　are　between　97%　and　102.2%.　This　method　is　simple,　fast,　accurate　and　ease　to　use.　Also　it　is　beneficial　for　the　application　in　middle　or　small-sized　electrolytic　aluminum　foil　enterprises.
