摘 要:用大孔超高交聯(lián)聚苯乙烯樹(shù)脂(簡(jiǎn)稱(chēng)HPS樹(shù)脂)進(jìn)行硝化反應,得到了硝化修飾的大孔超高交聯(lián)聚苯乙烯樹(shù)脂(簡(jiǎn)稱(chēng)HPS-NO2樹(shù)脂)。紅外分析、元素分析測定了HPS-NO2樹(shù)脂的硝化程度;通過(guò)交換量測定確定了HPS-NO2樹(shù)脂因氧化反應引入羧基的量。采用氮氣吸-脫附法測定了HPS、HPS-NO2樹(shù)脂的比表面積和孔結構參數。并考察了HPS、HPS-NO2樹(shù)脂對水溶劑、環(huán)己烷溶劑中苯酚和苯胺吸附機理及性能。 |
關(guān)鍵詞:超高交聯(lián)聚苯乙烯樹(shù)脂;硝化修飾;吸附 |

Abstract:A novel HPS-NO2 resin was prepared by nitro group-modifying the base macroporous hypercross-linked polystyrene resin. The HPS-NO2 resin was characterized using IR and elemental analysis. The content of carboxyl groups introduced on HPS-NO2 resin by oxidation reaction was determined by the exchange rate measurement. The specific surface area and pore structure parameters of the resin were determined by nitrogen adsorption-desorption method. The adsorption mechanism and behavior of HPS and HPS-NO2 on phenol and aniline in water and cyclohexane were investigated. |
Key words:hypercrosslinked polystyrene resin; nitrification modification; adsorption |
