| Summary: | As the growing rate of population growth, textile industry is one of the profitable industry in recent times there was almost every country have it. However, this industry generates hazardous waste to the environment, especially wastewater. The liquid waste is dominated by the dyes. Methylene blue dye is toxic, mutagenic, and carcinogenic. Adsorption method using encapsulated fly ash in protonated calcium alginate beads (CAFAP) may be an alternative treatment of waste containing methylene blue. The purpose of this research is to synthesize and study the performance CAFAP bioadsorbent against methylene blue adsorption. Adsorbent has been synthesized were characterized using Fourier Transform Infrared (FTIR) analysis and Scanning Electron Microscope (SEM), then adsorption performance of methylene blue was studied by using batch testing methods on various parameters. The results showed that 500 ppm was the initial concentration for optimum adsorption with optimum contact time of CAFAP occured on
4 hours, optimum adsorbent mass was 0,05 grams, and optimum pH was found to be pH
6-7. CAFA adsorption capacity obtained 153,2 mg/g with 76,6 % percent adsorption. While CAFAP produce adsorption capacity of 184,65 mg/g with 92,3 % percent adsorption. It showed that protonation can improve the performance of the adsorbent. Methylene blue adsorption process followed the Langmuir adsorption isotherm models and takes appropriate pseudo second-order reaction kinetics. CAFAP adsorbent can be reused after contacted with 1 M sulfuric acid.
