Determinação da composição química e aproveitamento de cinzas da queima da lenha de eucalipto para produção de água sanitária ecológica

Abstract

The burning of wood generate a significant amount of ash, where the main nutrient found is the calcium present in the form of quicklime (CaO) which gradually becomes calcium carbonate (CaCO3) and to add water to the lime, so hydroxide calcium (Ca (OH) 2) which is slaked lime. These features promote alkaline material action which may contribute to correct soil acidity. Performing analysis of the chemical composition of the ash and the product prepared by XRD, FTIR, atomic absorption and flame photometry, this paper develops a technique of reusing ash eucalyptus wood, producing a product similar to commercial bleach stimulating Eco posture.
