Abstract

Methylene blue is a material that is often used as a cationic dye in the textile industry. Methylene blue is toxic and difficult to degrade. Adsorption is one method to reduce the methylene blue from wastewater. In this study, methylene blue was adsorbed by calcium alginate/activated carbon composite (CaAlg-AcC) in a fixed bed column. The influence of CaCl2.2H2O concentration, initial concentration of methylene blue, and flow rate in the continuous adsorption process were investigated. Every adsorption process was done in 110 min. The results revealed that the CaAlg-AcC composite synthesized using 1% (w/v) CaCl2.2H2O solution has the highest adsorption percentage, 95.28% in 110 min. The initial methylene blue concentration 50 mg/L gave the highest result of adsorption percentage with the smallest amount of methylene blue adsorbed of 31.77 mg.  The flow rate of methylene blue 4 ml/min reached the highest adsorption percentage with the amount of methylene blue adsorbed of 41.79 mg.

Abstract

Methylene blue adsorption research has been conducted using bioadsorbents from activated carbon of coffee grounds and reeds. Coffee grounds and reeds contain carbon and cellulose that are effective for binding dyes. This study aims to determine the characteristics of activated carbon from coffee grounds and reeds based on SNI-06-3730-1995 and assess the color reduction of wastewater referring to the Decree of the Minister of Environment No. 51/MENLH/1995, which sets the maximum methylene blue content in industrial wastewater at 5-10 mg/L. The research method includes bioadsorbent preparation, characterization, and adsorption process with UV-Vis spectrophotometric analysis. Mass ratio variation was conducted on each adsorbent at each contact time variation and methylene blue concentration variation. The results of the analysis showed that the activated carbon of coffee grounds and reeds fulfills SNI-06-3730-1995 which is characterized by values that are below the maximum value in each parameter. The effectiveness of methylene blue adsorption by coffee grounds and reeds activated carbon reached 98.15% at a ratio of coffee grounds and reeds activated carbon 0:1 (w/w) for 120 minutes at a concentration of 25 mg/L. The adsorption capacity using the Freundlich isotherm method on reed activated carbon was 1.100 mg/g and coffee grounds activated carbon was 1.019 mg/g. The adsorption process of coffee grounds and reeds activated carbon has no effect on the carbon and cellulose structure of coffee grounds and reeds contained in activated carbon, namely O-H, C-H, C=C, and C=O.
