Ma. Artemeva et al., PHOTOSTIMULATED PRECIPITATION OF SILVER ON NIOBIUM(V) OXIDE FROM AQUEOUS-SOLUTION, Journal of applied chemistry of the USSR, 65(11), 1992, pp. 1995-2001
A study has been made of the precipitation of silver from its aqueous
nitrate solutions (5.10(-5)-1.10(-1) M) on the particles in a niobium(
V) oxide suspension (high-pressure monoclinic modification, S-0 = 3.5
+/- 0.5 m(2)/g, z.c.p. of 3.95) under the action of light with lambda
> 320 nm (DRK-120 mercury bulb, BS-5 glass filter).
