[0017] Example 1
[0018] Add 62.3 mg of mercury nitrate containing 0.5 crystal water to 10 mL of deionized water, and then add 2 mL of an alkaline solution of L-cystine with a molar concentration of 0.09 mol / L. The alkaline solution of L-cystine is It is prepared by dissolving 8mL L-cystine in 1.3mL sodium hydroxide aqueous solution with molar concentration of 2mol / L, and then adding 1mL molar concentration of thioacetamide aqueous solution with 0.18mol / L, and stirring in a 38℃ water bath. For 15 hours, centrifuge at 4500 rpm, take out the supernatant, and disperse the centrifuged product in 10 mL of deionized water, and finally prepare the chiral metal compound nano-material mercury sulfide.
