废瓷粉/玻璃复相多孔陶瓷对不同香精选择性吸附的研究
Selective Adsorption of Different Flavors by Waste Porcelain Powder/Glass Composite Porous Ceramics
摘要
Abstract
By adjusting the ratio of waste porcelain powder and glass powder,porous ceramics with different porosities were sintered at a series of temperatures gradients from 910℃to 990℃.Porous ceramics with different porosities were used as adsorbents to evaluate their adsorption/desorption performance for six flavors.The retained components within the porous ceramics were elucidated,and a release model for these flavors from the porous ceramics was established.The results indicate that the porous ceramics with 40%porosity exhibits the highest specific surface area,reaching 2.33×106 mm2/g,along with the greatest adsorption capacity(223.98～301.82 mg/g)and the shortest adsorption time(2.68～9.90 s)for all six flavors.The dense pore network of the high porosity porous ceramics effectively shortens the diffusion path of the flavors,facilitating a faster adsorption rate.In the flavor release experiments,the release rate of the three alcohol-soluble flavors approach 100%,whereas those of three water-soluble flavors all remain below 70%.The main retained components of the three water-soluble flavors in the porous ceramics are DL-glyceraldehyde,L-lactic acid,and 5-hydroxymethylfurfural,respectively.These retained components contain two types of polar functional groups from among hydroxyl group(—OH),aldehyde group(—CHO),and carboxyl group(—COOH),and they form a strong hydrogen-bonding network with the hydroxyl group on the surface of porous ceramics,which enhances the adsorption efficacy of the porous ceramics towards them.关键词
