Abstract:Pollution is defined as the entry of an object, substance or energy into the aquatic environment that has a negative impact on living things. This study aims to determine the adsorbent absorption of crab shell ash and kupang ash to the levels of heavy metal chromium (Cr), CrChromium (Cr), Cadmium (Cd), Cobalt (Co), Iron (Fe), Copper (Cu), Manganese (Mn) and Nickel (Ni) in standard solution. Shell ash is made by calcination using a furnace at 900 ° C for ± 9 hours. The standard solution was added to the shell t… Show more
