• 中文摘要： 本研究以泡沬分離技術處理各含 50 ppm 之鈷、鎳及六價鉻離子之合成廢水。以分批式之泡沫分離設備來處理該廢水在酸鹼值為九時分離效果最好；經過十分鐘之處理可同時將各種離子去除百分之九十九點八以上。當合成廢水之離子強度不高於0．1M時，以連續式之泡沫分離設備，可將上述合成廢水之各離子去除百分之九十九點九以上；各離子之殘留濃度皆低於0.05 ppm。
• 英文摘要： The simulated wastewater containing 50 ppm each of Co (Ⅱ), Ni (Ⅱ), and Cr(Ⅵ) was first treatedby a batch type foam flotation plant．Best removal efficiency was achieved at pH 9.0, being over 99.8%for all three metal ions. The solution was also treated by a continuous flow type foam separation plant.Residual metal ions less than 0.05 ppm (with separation efficiency over 99.9%) could be achieved providedthat the ionic strength of the solution was no greater than O.1 M.
