Effectiveness of Sequential Pre-treatment and Application of High-porosity Hybrid Fly Ash Geopolymer/alginate Adsorbent for the Treatment of Batik Wastewater
In this work, hybrid fly ash geopolymer / alginate spheres (GSA) were produced and used as an effective and economical adsorbent in a treatment of batik wastewater. A preparation of GSA adsorbent involved a facile method where the fly ash (FA) based geopolymer was entrapped into sodium alginate (SA)...
