Abstract

Mobile phones and batteries have relatively short life cycle and quickly seen as outdated by consumers, especially teenagers. It is not easy to dispose or discard in everywhere because mobile phones and battery have a range of hazardous and precious metals which are lead, copper and precious metals such as gold, silver, aluminum, copper and others. This study was to investigate the rate of solution hazardous metals and from PCB mobile phone and batteries using hydrometallurgical methods. Hydrometallurgical method is the method used by the process of dissolution of metal with a sample to be tested must be separated between metal and nonmetal materials. Leaching processes is a major step in the hydrometallurgical method. The solution has been taken should be analyzed using laboratory equipment which is ICP to determine the total concentration of hazardous metals. Findings of this study is the total concentration of hazardous metals contained in the most high sample is Lead. The hazardous metals lead and copper have many negative impact to the human body. So, everyone should have an awareness to ensure the proper disposal method for each component of electrical and electronic equipment such as mobile phones.
