【摘要】 为了研究柠檬渣吸附Cr⁶⁺的荧光性能及变化规律,分别测试了柠檬原渣、K₂SO₄、H₂SO₄、H₃PO₄、H₃BO₃、KOH和ZnCl₂改性柠檬渣吸附Cr⁶⁺后的荧光性能,并进行了数学仿真。试验结果表明,柠檬原渣和化学改性后的柠檬渣吸附Cr⁶⁺后均具有明显的荧光吸收峰,回归方程均能较好地反映出各柠檬渣中荧光物质的变化规律。更多还原

【Abstract】 In order to study the fluorescence properties and variation of Cr⁶⁺ adsorbed by lemon residues,the fluorescence properties of the original lemon residues,and the respectively modified lemon residues by K₂SO₄、H₂SO₄、H₃PO₄、H₃BO₃、KOHand ZnCl₂ were tested,in the same time the regression analysis was used.The results showed that the original lemon residues and chemically modified lemon residues adsorbed by Cr⁶⁺ were obvious fluorescence absorption peak.All the regression equations could reflect the change rule of fluorescent substances in lemon residue.更多还原
