Solid phase extraction and removal of brilliant green dye on zinc oxide nanoparticles loaded on activated carbon: New kinetic model and thermodynamic evaluation

摘要

The brilliant green (BG) solid phase extraction of carried out following accumulation on including zinc oxide nanoparticles loaded on activated carbon (ZNO-NP-AC) non-toxic and green as material. The influence of variables such as pH, initial BG concentration, contact time, amount of adsorbent, eluent and temperature on BG removal and recoveries were studied and optimized. The high correlation coefficient and possibility of accurate prediction and explanation of experimental data by novel kinetic model show its applicability and superiority for representation of experimental data. The results of present model compared with traditional kinetic models (pseudo-first and second order and intraparticle diffusion model).
