Abstract
Mercury has a significant negative effect on the health of humans and living things, and is a dangerous element that is widely known. Mercury is commonly found in gold mining wastewater. One way to remove mercury from waste water is to use the adsorption process. One of the adsorbents used in the absorption of mercury is palm shell fly ash. Palm shell fly ash is solid waste from the result of burning palm shells on the boiler. The use of fly ash from palm shells as an adsorbent is preferred because it is cheap, environmentally friendly and available in large quantities. The adsorption process is carried out by contacting the adsorbent directly with waste water. Addition of adsorbents to wastewater can increase the pH of wastewater to 4 levels. The best adsorption results are indicated by the efficiency of mercury ion absorption up to 100%. The adsorption capacity of the adsorbent increases with increasing time of stirring the adsorbent in wastewater.
