Abstract

Cual batik liquid waste discharged directly into the environment can cause environmental problems due to containing various heavy metals such as iron metal (Fe). Adsorption method is one of the efforts to reduce heavy metal content in wastewater. This study utilises activated carbon from coconut shell waste to be used as a heavy metal adsorbent. The activated carbon used is the result of physical and chemical activation processes. Based on SEM results, activated carbon has pores with a pore diameter of 81.84 µm and a surface area of 0.2315 cc/g. The adsorption process was carried out using activated activated carbon with mass variations of 0.25 grams, 1.5 grams, and 1.75 grams. Meanwhile, the contact time variations used were 0, 40, 80, 120, and 160 minutes. The results showed that the most optimum mass variation of activated carbon to absorb Fe metal was 1.5 grams with a contact time of 80 minutes which left a residual Fe metal of 0.161 ppm.

Abstract

Activated carbon from coconut shell waste is a porous solid that has a large surface area with high absorption capacity, making it an alternative for reducing levels of heavy metal ions in the air. Active carbon is made by carbonization and chemical activation, then SEM testing is carried out to see the morphology of the activated carbon and analyzed using ImageJ software. This research aims to determine the effect of chemical activation and no activation on the number of pores formed in activated carbon. From the results of research that has been carried out, there are more pores formed after carbon is activated compared to carbon without activation. This is because the carbon surface without activation is still covered by impurities. In addition, unactivated carbon and activated carbon from coconut shells have pore sizes that fall into the mesoporous category.
