[求助] 求助有关间歇性实验的具体过程

Batch adsorption experiments were performed using 40 mL glass vials equipped with polytetrafluoroethylene-lined screw
caps. Vials received 20 mg of adsorbent and a full volume of background solution containing 0.02 M NaCl , followed by organic
solute in a methanol carrier (2-naphthalenesulfonate in distilled water) that was kept below 0.1% (v/v) to minimize possible
cosolvent effects on adsorption. The pH of aqueous solution was adjusted with 0.01 M HCl and 0.01 M NaOH. The samples were
covered with aluminum foil from light and were mixed end-overend at room temperature for 24 h. This period of time was sufficient
enough to reach apparent adsorption equilibrium (no further uptake) based on kinetic measurements.
这是文献中的间歇性吸附实验,里面的溶液如何加入不明白,不理解,应如何操作,请大神指点!如果可以请具体的给翻译一下,谢谢!

英文不复杂,知道以下关键词后应该读得懂:

Batch adsorption: 批次吸附或平衡吸附

polytetrafluoroethylene-lined screw caps 聚四氟乙烯内衬的旋盖

aluminum foil 铝箔

end-overend头尾式摇摆混合器

关键的这句:  除2-naphthalenesulfonate 用 distilled water之外,其他用甲醇助溶,体积控制在 0.1% (v/v)之内,避免助溶剂的效应。

离成功还差一点

您好,单词的意思都懂的,只是Vials received 20 mg of adsorbent and a full volume of background solution containing 0.02 M NaCl , followed by organic
solute in a methanol carrier (2-naphthalenesulfonate in distilled water) that was kept below 0.1% (v/v) to minimize possible
cosolvent effects on adsorption. The pH of aqueous solution was adjusted with 0.01 M HCl and 0.01 M NaOH. 这句中,溶液时怎么加的不清楚。它首先在瓶内加了 20 mg吸附剂和0.02 M NaCl,并且0.02 M NaCl是充满瓶中的,那甲醇是加到哪里去了,0.1% (v/v)的体积比是指的那种物质的体积比?谢谢!

40 ml 瓶子不一定刚好装40 ml ,每瓶放20mg吸附剂,加40 ml  0.02 M NaCl ,然后将有机溶质,(除了2-naphthalenesulfonate 用水溶之外), 用不超过0.04ml(40ml的甲醇溶解后加入,然后pH用0.01 M HCl 和0.01 M NaOH调节.
