Avaliação da lixiviação do cádmio e níquel provenientes da degradação de baterias níquel-cádmio em uma coluna de solo

摘要: EVALUATION OF THE LEACHED CADMIUM AND NICKEL FROM DEGRADATION NICKEL–CADMIUM BATTERIES IN A COLUMN SOIL. Spent nickel–cadmium (Ni–Cd) batteries and salts of nickel cadmium were placed in two different columns soil for a period years. leaching solution was passed through them at ambient temperature this period. The behavior metals each column then evaluated. Under the conditions experiment, demonstrated potential to contaminate affect natural cycles soil. disposal Ni–Cd directly also increased concentration (349 mg kg−1) (2890 kg−1), sometimes exceeding intervention values defined CONAMA resolution 420/09.
