MIGRASI MONOMER STIREN DARI-PLASTIK POLISTIREN KE DALAM BEBERAPA SIMULASI MAKANAN

Migration of styrene monomer from polystyrene plastic into several food and beverages simulations has been carried out in this study. Parafin liquid, 50 % alcohol, 5 % sodium carbonate, 5 % citric acid solutions and aquadest were used as extraction solvent to simulate food and beverage. Measurement...
