Further, 0.16~0.19 molL is contained in the mixed solution-1Cu2+Ion and 0.2 molL-1Ce3+From
Son.
Further, the mantoquita is cupric salt.
Further, the cupric salt is Gerhardite, Salzburg vitriol, the one of Copper dichloride dihydrate
Kind.
Further, the cerium salt is Ce (NO3)3·6H2O。
Further, the aqueous slkali is 4 molL-1The mol ratio of sodium hydroxide solution, cerium salt and sodium hydroxide is 1:
8.0。
Further, the addition aqueous slkali refers to rapidly join sodium hydroxide solution molten just in the mixing of magnetic agitation
Liquid.
Further, cooling refers to reactant mixture being transferred to poly- after described reactant mixture heating a period of time
In the reactor of tetrafluoroethene liner, 1~4h of heated at constant temperature, then naturally cools to room temperature at 100~180 DEG C.
Further, take out, centrifuge after the cooling, dried after washing and refer to after cooling, take out in reactor
Solidliquid mixture, centrifuge, distilled water and absolute ethyl alcohol respectively washing 3 times, be dried in vacuo 2 hours at 60 DEG C.
