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 ´ÓÕâÀïµÄÒºÏà×ö·¨Öп´³öilÓ¦¸ÃÊÇÿºÁÉýµÄÒâ˼ https://cache.baidu.com/c?m=9d78 ... 3e61&user=baidu |
