Abstract
The waters in Cempaka Sub-district have been contaminated by heavy metals that exceed the quality of waste water standard. The process that can be used to reduce waste pollution is by phytoremediation method. Phytoremediation is a method of waste degradation using plant capability. One of the plants is the parupuk plant (phragmites karka). Parupuk plant (Phragmites karka) has a big ability to degradation the waste. Parupuk plant was included in poaceae family. The purpose of this study is to analyze the influence of mass variations and the duration of immersion of parupuk plants in absorbing heavy metals mercury. In this study begins with static phytoremediation was performed by plant mass variation of 0.5 kg, 1 kg and 1.5 kg. The Soaking period of 8 hours, 80 hours, 152 hours and 224 hours. From the result of research known, the effective condition for the parapuk plant to absorbs the heavy metals mercury is at the 8th hour of phytoremediation and 1.5 kg parupuk plant can absorb the heavy metals mercury by 90,74%.
Highlights
Mercury is a compound as well as other metals which are toxic and are widespread
Based on research[6], in the District Cempaka polluted waters, heavy metals that exceed the threshold of waste water quality standard is 0.02 mg/l according to PP 82 of 2001 on the waste water quality standards for mercury content
For the analysis of mercury levels in this study was done by the Atomic Absorption Spectrophotometer (AAS) method
Summary
The use of mercury has grown very broad, and one of them in the traditional gold mining process[1]. It was recorded several events of Mercury poisoning that occurred in the World such as the case in Minamata that killed 111 people, in Iraq, 35 people died 321 injured, and Guatemala 20 people died 45 injuries caused mercury poisoning[2]. Based on research[6], in the District Cempaka polluted waters, heavy metals that exceed the threshold of waste water quality standard is 0.02 mg/l according to PP 82 of 2001 on the waste water quality standards for mercury content
