Encapsulation powder skin duck eggshells on alginate as adsorbent methylene blue

The textile industry has a major role in water pollution problems. River water is contaminated with sewage can cause damage to the aquatic ecosystem and if entry into the food chain cycle can be carcinogenic and mutagenic compounds. Methylene blue (MB) is one of the dyes are widely used in the textile industry and is of great concern in the process of wastewater treatment because it is difficult outlined in nature and harmful to the environment. Methylene blue adsorption from solution via adsorption using adsorbents calcium alginate (CA) and eggshell powder encapsulated in calcium alginate (CA-SCT) and eggshell shell powder (SCT) has been studied. The results showed that the optimum contact time SCT, CA, and CA-SCT occur at the contact time of 2 hours. The optimum adsorbent mass of 0.05 grams, and pH optimum at pH 6-7. SCT percent adsorption, CA, and CA-SCT are respectively 25.07%; 60.07%; and 69.66%. Consider it encapsulation can improve the performance of the adsorbent. (paper)
