Summary: | Uric acid (2,6,8-trioxypurin) is the final metabolic result of purine nucleotides, which will be excreted in the urine. Purines are a nucleoprotein group that comes from food and the destruction of old body cells. Excess uric acid in the body shows symptoms of several diseases such as diabetes, high cholesterol, and liver disease. Some epidemiological studies also show that excess uric acid can cause leukemia, pneumonia, and the risk of kidney failure. In this study, the development of voltammetric methods on filter paper media for uric acid analysis using carbon paste electrodes (EPK) and modified carbon paste electrodes. EPK modification is done by forming a mold on the surface of the electrode namely Nonmolecularly Imprited Poly (3-aminophenol) (EPK-NIP) and Molecularly Imprited Poly (3- aminophenol) (EPK-MIP). Analytical measurements are carried out using a differential pulse voltammetry ( DPV) in the range of 100 m V - 500 m V with a scan rate of 50 mV I s. The electrode performance test has been carried out and gives a linear area in the concentration range ofO. l - 0.5 mM. The measurement results on urine samples on filter paper media showed good results with percent recovery of around 97.54% to 103.95%. Applications in the field of teaching go through making videos on electrolysis. |
