Abstract

Today, waste of industries generates contamination to environment, especially river stream. One of them was the electroplating industries. Generally, it still contained nickel metal above the concentration's limit. The government has settled it which was 0,5 mgram of nickel metal/liter of solution. The effect of accumulation nickel in our body was skin allergies, asthma, heart and liver damage. So, we need an effort to reduce nickel metal's concentration before thrown to environment. One of the treatment was an adsorption method. This research's aim was to know the value of mass transfer coefficient on nickel metal adsorption in continue system with active carbon as the adsorbent. The variable that observed was rate of flow. Every period of time, the liquid flowed from the column was analyzed using AAS, so we knew nickel metal concentration after adsorption process. In this research, mathematical model representing the adsorption process was made. The correlation between rate of flow and kc8 was represented with Non Dimensional Group equation, which is :
