In recent years managing ecological changes and comprehending diverse anthropogenic contributions towards pollution is now of great concern due to industrialization. Therefore, creating an environmentally friendly solution for dealing with harmful substances like Methylene Blue in water has become a critical issue. This experimental investigation aims to design and assess the unmodified clay mineral of the Panchaganga River flood zone for the removal of MB by batch tests. The removal of MB was examined by optimizing all the variables, further XRD, SEM, EDX, BET, and FTIR, were all used to meticulously examine the NC before and after adsorption. Methylene Blue content was determined by UV-visible spectrophotometrically, and the mechanism of NC's adsorption to MB in water was examined by modeling isotherm and kinetics studies. At pH 7.00 to 8.00, the NC showed a high extraction of MB due to negatively charged clay surface (Si-O-), (Al-O-). The adsorption capacity qm obtained was 88.8 mg/g (Langmuir). The kinetics study showed that the adsorption mechanism follows pseudo-2nd-order indicating chemisorption as a rate-determining step, moreover, adsorption also occurs via the intra-particle-diffusion process due to small pores on NC. The study demonstrates that the NC exhibits significant efficacy in efficiently removing the cationic dye (MB) pollutant from waste-water systems. [ABSTRACT FROM AUTHOR] |
