Embodiment Construction
[0028] The present invention will be further elaborated below in conjunction with embodiment, but should not limit protection scope of the present invention with this.
[0029] Embodiments of the present invention are as follows:
[0030] Spectrophotometric detection of trace amounts of platinum in laser glass samples. The complexing agent uses 2-[2-[4-[(2-cyanoethyl)-methyl-amino]-phenyl]-vinyl]-1,3,3-trimethyl-3H-indole Chloride, produced by TCL, was purchased from China Reagents.com; the ultraviolet-visible spectrophotometer was PerkinElmer Lambda 950UV-VIS-NIR, with a wavelength range of 400-650nm.
[0031] A. Solution preparation:
[0032] 10mg·L -1 Pt (IV) standard solution: take an appropriate amount of 1000mg L -1 Pt (IV) standard solution (manufactured by Macklin), add deionized water, dilute to obtain 10mg L -1 Pt(IV) standard solution.
