Adult minimum daily requirement of folic acid is about 50 micrograms per day of folic acid food content of about 200 - 400 micrograms of folic acid, but not all, are being used, such as improper cooking loss volume could reach 50 - 90%, according to the World Health Organization recommends a daily folic acid requirements for: Infant 60 micrograms, 100 micrograms for children, general adult 200 micrograms, 400 micrograms for pregnant women, lactating women 300 microgram .

成人的每日叶酸最小需要量约为50微克，每天吃的食物中叶酸含量约为200–400微克，但不是所有的叶酸都被利用，如烹调不当，损失量可达到50–90％，根据世界卫生组织的建议，每日叶酸需要量为：婴儿60微克，宝宝100微克，一般成人200微克，孕妇400微克，哺乳妇女300微克。

According to the graph of adsorption speed, a conclusion can be drawn that formic acid and acetic acid are fixed on the resin with multimolecular adsorption while propanoic acid and pentanoic acid are carried by monomolecular adsorption.

通过其吸附速度、吸附等温线的研究，得出甲酸和乙酸在该树脂上以单分子吸附为主，丙酸和成酸以多分子吸附为主，而且吸附的强弱与羧酸的解离有关，解离越强吸附越弱，反之，吸附越强。

After removing the catalyzer by dense muriatic acid, carbon nanotubes are reacted with mix acid (vitriol:nitric acid=3:1 vol./vol.). By comparing the surface image of gained carbon nanotubes under the different condition, the best mix acid oxidation temperature is fixed on 140°C and the reaction time is 30min. The soluble carbon nanotubes were prepared by decorating of octadecylamine on the surface of nanotubes. Three processes of grafting were investigated in this research.

对碳纳米管的热失重、差热分析结果表明，通过在一定温度下空气氧化可去除大部分碳颗粒；而浓盐酸浸泡可去除碳纳米管制备过程中残留的催化剂颗粒；对在不同条件下与硫酸和硝酸配制的混酸反应处理后得到的碳纳米管的表面形貌研究表明最佳混酸氧化条件为140℃氧化30min。
