Efficient adsorptive removal of methylene blue from synthetic dye wastewater by green alginate modified with pandan

Remediation of dye-bearing wastewater is important to preserve the water quality. This study reports the performance of new adsorbent, namely alginate polymer modified with pandan leaves (AlgiPAN), in removal of methylene blue (MB) from synthetic solution. The adsorbents in beads form demonstrated high removal percentage (61%) towards MB (0.01 g/L) at 60 min reaction time, pH 5 and adsorbent dosage of 3 g. This study demonstrates the capability of AlgiPAN in MB dye removal without involving complex synthesis processes. Such adsorbent can be easily separated after wastewater treatment, and the pandan modification increase the surface functional groups. (C) 2019 Elsevier Ltd. All rights reserved.
