这里应该是分液的意思 aliquot ,就是分成等分咯An appropriate aliquot (typically 1 to 5 mL) 看这里有助于了解https://cache.baidu.com/c?m=9f65 ... 7d53&user=baidu
All reagents were of very high purity such as "Analytical Grade," "Analyzed Reagent Grade" and others. And assay of nitrite was determined according JISK8019 and assays of nitrite salts were 98.9%. We use that value to adjust the weights taken. For the silicate standards solution, we use commercial available silicon standard solution for atomic absorption spectrometry of 1000mg L-1. Since this solution is alkaline solution of 0.5 M KOH, an aliquot of 40ml solution were diluted to 500ml as B standard together with an aliquot of 20ml of 1M HCl. Then the pH of B standard for silicate prepared to be 6.9. Ultra pure water


从这里的液相做法中看出il应该是每毫升的意思
