Coconut Biosorption Essay

Heavy metals will become one of factor this pollution happenand give effect to human and environment. To prevent this problem to increase continually, it needs the effective method to prevent this problem become more critical. Many method have been apply in industrial. Most of the method is costly. Biosorption is the new alternative method to remove heavy metals. Biosorption method is high efficiency, and low cost. Coconut fronds are one of agriculture waste. So, it cannot be a waste anymore when it can use to be are adsorbent for heavy metals.

1.5 Objective Of Study
The objectives of this study are: To determine the optimum parameter (pH, contact time and adsorbent dosage) of Cr (III), Pb (II) and Cd(II) adsorption on treated coconut fronds. To identify the optimum adsorbtion capacity of coconut fronds (cocos nucifera) based on Langmuir Model

Introduction

In the last decade the developments of technology become faster. Some of the technology may have cause negative effect to the environment. The major problem with technology is heavy metals problem. Heavy metals problem usually come from the industrial activity and urbanization. These heavy metals may cause pollution to the environmental material such as soil, water and air. These three environmental materials very related with human life. When the heavy metals contain inside soil, water or air it will go into human body and become hazardous to them. To prevent this problem, many methods are being used to remove the heavy metals in the industrial effluent from containable the environmental
