In recent years, the utilization of biochar in soil, both in grasslands and cultivated areas, has garnered attention as a promising method to combat global warming. This stems from its porous carbon structure, which includes biochar and activated carbonActivated carbon is a form of carbon that has been processed to create a vast network of tiny pores, increasing its surface area significantly. This extensive surface area makes activated carbon exceptionally effective at trapping and holding impurities, like a molecular sponge. It is commonly More, renowned for its effectiveness in adsorbing gases and liquids.

A growing interest has emerged in examining the adsorption capabilities of biochar, prompting a comprehensive review focusing on kinetic models to assess its adsorption performance. This review delves into key kinetic models such as pseudo-first order, pseudo-second order, Elovich, and intraparticle diffusion, elucidating their applications in evaluating adsorption activity as a function of time.

One notable investigation involved phosphate adsorption on a Ca-loaded rice husk biochar, prepared through the carbonization of rice husk immersed in a CaCl2 solution at 1000 °C. Through the application of these kinetic models, the study sheds light on the efficacy of biochar in adsorbing phosphate, offering insights crucial for its potential implementation in mitigating global warming effects.

This analysis underscores the significance of biochar as a sustainable solution in addressing environmental concerns, emphasizing the need for further research to maximize its effectiveness in combating climate change.
