  1. laMolar fraction of 1-allyl-3-methylimidazolium chloride ([AMIM]Cl)/OES.
  2. lbIn total, 468 runs were conducted. The data in each cell are based on six runs from two parallel experiments, each of which gave three parallel tests, respectively. Mean values with the same superscript letters on the same horizontal row are not significantly different. The 95% confidence level was set at P < 0.05.
