Abstract

Six types of cans were used to obtain the shot (sardine, tomato, milk, varnish, paint and juice). Parameters of time, temperature and reaction media (HCl, NaOH, seawater and tap water) were screened as the optimal physical parameters in the experiments. Heated to 500 °C and introduced into the NaOH solution (0.2mol/L), shot was obtained after a six-month waiting period from juice cans. Increasing the temperature at 1080 °C, the shot was extracted with the five other types of metal cans used. This research showed that the temperature and basic medium were the optimum conditions for obtaining shot. It is deserved t to study the chemical composition of the metal cans in greater depth, with a view to use in the agriculture or craft industry in the future.
