Removal of Methylene Blue of Textile Industry Waste with Activated Carbon using Adsorption Method

Abstract

The colorant that is often used in the textile industry is methylene blue which is a cationic heterocyclic aromatic compound. This compound is very stable and is difficult to decompose naturally leading to environment in large concentrations. Therefore, a waste treatment technology to reduce the concentration of dye waste in water becomes importannt. So far, adsorption method with activated carbon remains the most efficient and effective technique in removing dyes from liquid waste due to its relatively large adsorption capacity. Activated carbon is one of the non-metallic mineral commodities or multipurpose industrial minerals, one of which is as an adsorbent or adsorbent media. This study aims to determine the potential of activated carbon in adsorbing methylene blue with variations in the concentration of methylene blue and particle size of activated carbon. The procedures in this experiment include, the preparation of activated carbon with size variations (20-60, 60-100 and> 100 mesh) and variations in the concentration of methylene blue (15 ppm, 30 ppm and 45 ppm) with contact time (0 to 180 minutes). From the results of the study, it was found that the smaller the size of activated carbon used, the greater the adsorption capacity, ie at mesh size> 100 mesh, the adsorption capacity was 9.8%. Whereas, the smaller the concentration of methylene blue, the activated carbon could work optimally at a concentration of 15 ppm at 30 minutes with adsorption capacity as high as 100%.Keywords: adsorption; Methylene Blue; activated carbon; concentration; time; particle size

Highly Efficient Photocatalyst Fabricated from the Chemical Recycling of Iron Waste and Natural Zeolite for Super Dye Degradation

“…On the other side, dye pollutants are becoming a major source of environmental contaminations [3,4]. Methylene blue (MB) is amongst the most commonly used dyes in textile industries.…”

“…Organic dyes are removed via physical, chemical, and biological techniques. Some of the techniques utilized include adsorption, filtration, membrane separation, coagulation, dilution, flotation, softening electrochemical, reverse osmosis, and photodegradation [3,7]. The technique of photodegradation is commonly used to remediate organic dyes from wastewater into harmless inorganic molecules such as CO 2 and H 2 O [7,8].…”

The Capability of Mangrove Charcoal in Adsorption Process of Indigosol Substance in Wastewater of Batik Industry

“…The content of dyes in liquid waste is estimated at 20-30 mg / mL (Widjajanti et al, 2011). Various color substances are used in the textile and batik industries, including methylene blue, naphthol, indigosol, and others (Maryudi et al, 2019;Herfiani et al, 2017). Excessive use of synthetic color substances can cause problems from the resulting waste (Mozammel et al, 2002).…”

“…Activated charcoal with Fe activation and the addition of hydrogen peroxide has been used to treat liquid waste containing dyes with fairly good results. Activated charcoal has been widely utilized for liquid waste processing with various combinations with fairly good results (Maryudi et al, 2019). The adsorption process that occurs can be physical and chemical adsorption.…”
