Experimental study of methylene blue adsorption by various adsorbents

In this study, various adsorbents were studied on methylene blue contaminants. Experiments were carried out at a concentration of 10 ppm and 0.1 g of adsorbent in a 30 minute period. The results showed that the adsorbent adsorbent had a better absorption rate and compared with hydrogel absorber (chitosan / sodium alginate) with two chitosan and sodium alginate adsorbents, the percentage of hydrogel adsorption was 82.15% and compared with hydrogel absorption with the presence of surfactant in the absence of surfactant The results showed that the presence of SDS increased the absorption rate to 95.68%. Also, in the study of active carbon, tests showed that activated carbon hydrogel had a higher percentage and equal to 97.4%.
