Avaliação da liberação de NH4NO3 ocluido em zeólita 4A a partir de soluções salinas Assessment of release of NH4NO3 occluded zeolite 4A in solutions from salinas
Abstract
The zeolite 4A was used to evaluate the thermo kinetics parameters of NH4+ and NO3- ions occluded in its structure. The Osawa method for activation energy calculation was used to evaluate its thermal stability, and the results shown that the ion species interact differently depending on the zeolite pores, which determines the controlled release by its structure.
