Color Removal from Synthetic Dye And Textile Wastewaters Using Adsorbent Prepared From Psyllium Husk

Penyingkiran warna dari efluen tekstil telah diberikan banyak perhatian dalam beberapa tahun lepas oleh proses penjerapan menggunakan adsorbents kos rendah. Dalam kajian ini, bahan penjerap sekam psilium/CoFe2O4 (PH/CFO), disintesiskan melalui satu langkah mudah laluan refluks dan telah digunakan se...
