Chlorophenols are toxic, recalcitrant and hazardous compounds. They are available in soil, water and wastewater as persistent pollutants because of their non-biodegradable nature. The International Agency for Research on Cancer (IARC) has determined that the chlorophenols as a group, are possibly carcinogenic to man. Removal of chlorophenols using calixpyrrole modified silica was performed. Modified silica has different novel properties for various applications. In the present work, we have synthesized new modified silica followed by characterization with FT-IR, solid state NMR, XRD, SEM and TGA techniques. The Modified silica was used for removal of chlorophenols from aqueous solution. The influences of temperature, pH, chlorophenols concentration and mass of the adsorbent have been investigated. Parameters such as pH and quantity of modified silica show a noticeable influence on the adsorption capacity of this material. High adsorption capacity of modified silica for chlorophenols provides a solution for commercially feasible water filters.
