A Review: Extraction of Platinum Spent Catalyst Using Palm Oil Leaf as Reducing Agent

Platinum is commercially used in the catalytic industry for ages. The use of platinum has been significantly practiced because of its enhancing properties. There are a few advantages of using platinum such as high selectivity, high yield, high stability and able to undergo improvisation. However, when platinum lifetime is out, it is treated mainly as waste. Low recovery of platinum spent catalyst brought to the existence of recovery method using acidic and alkaline method. Proved to be harmful, green subtances were used as substitute for the chemical in recovering platinum. Therefore, a cheaper, safer and more environmentally method of recovery. Thus,this paper review about recovering platinum using palm oil leaf and how it is better than the existed chemical based method.
