Adsorption studies of ammonia and phosphate ions onto calcium alginate beads
This study aims to utilize the calcium alginate (Ca-Alg) beads for ammonia and phosphate
ions adsorption. The alginate beads were characterized using the scanning electron
microscope (SEM) with Energy Dispersive X-Ray (EDX) spectroscopy. The alginate beads
showed relatively high removal efficiencies for ammonia ions (94.94%) and phosphate ions
(88.31%). For the ammonia ions adsorption, the optimum condition was at the original pH
(6.0), alginate beads amount of 5 g/L, ammonia ions concentration of 50 mg/L, and a contact …
