Microgels have gained significant importance for the removal of pollutants owing to their stimulus-responsive behavior, high stability, and reusable capacity. However, despite these advantages, several hurdles need be overcome fully maximize potential as effective adsorbents eradicating various contaminants from environment, such metallic cations, organic compounds, anions, harmful gases, dyes. Therefore, a critical review on adsorption by microgels is needed. In this regard, presents latest developments in adsorptive properties microgels. The synthetic methods, architectural structures, behavior are explained detail. addition, explores factors that directly influence microgels, pH, feed composition, content pollutants, comonomers, agitation time, temperature, microgel dose, nature both adsorbates (pollutants) (microgels), medium, ionic strength. Various isotherms also explored together with kinetic aspects process provide comprehensive understanding.
