Abstract
In this study, in order to develop a new inorganic carrier to adsorb sulfur-containing organic compounds, the nano-attapulgite/CaCO3 carriers were developed with clay, nano-attapulgite, nano-calcium carbonate and silica as raw materials. The best raw material ratio of nano-attapulgite/CaCO3 carriers was optimized by single factor test and response surface experiments, and the deodorization effect of nano-attapulgite/CaCO3 carriers was further verified. The results showed that the optimal ratio of raw matrixes was 9.77 g of clay, 4.15 g of attapulgite, 2.80 g of nano-calcium carbonate, and 2.08 g of silica. The nano-attapulgite/CaCO3 carriers were prepared by calcining these mixed materials at 800 °C for 4 hours, and the water absorption was up to 31.78%. Besides, the deodorization effect of nano-attapulgite/CaCO3 carriers on fermented onion odor was as high as 45%, and the deodorization effect on rotten egg odor is up to 30%, indicating that the carrier has a high deodorization effect on sulfur compounds.
