【求助】谷胱甘肽和氯金酸反应出现白色浑浊物,如何避免?
|
|
按照 Ghosh A, Udayabhaskararao T, Pradeep T. One-Step Route to Luminescent Au18SG14 in the Condensed Phase and Its Closed Shell Molecular Ions in the Gas Phase[J]. Journal of Physical Chemistry Letters, 2012, 3(15):1997-2002.的方法。参考“1.2 mL methanolic solution, containing 150 mg of HAuCl4.3H2O, 1.8 mL water was added. 300 mg of glutathione was added to it. The solution was sonicated to dissolve glutathione. During sonication, the color of the solution changed from yellow to almost colorless.” 我在制备好甲醇、水、谷胱甘肽的澄清溶液, 往其中加入1滴氯金酸溶液,立刻出现白色浑浊。试了很多次,溶液一直没有出现澄清,每次都是一接触就白色浑浊。这是为什么?如何解决 |
