A low-cost adsorbent from coal fly ash for mercury removal from industrial wastewater

Mercury is recognized as one of the most hazardous heavy metals. A variety of water treatment technologies exist that propose effective mercury removal. However, they may not be practical in many developing countries, largely due to their high implementation costs. We propose a cost-effective mercury removal approach based on a synthesized zeolite Linde Type A (LTA) from coal fly ash (CFA-ZA). The effectiveness of the proposed approach was...
