in water Sonication; aq. soln. Bi(NO3)3*5H2O and Na3PO4*12H2O was adjusted to pH 0.5-1 with 6M HCl and exposed to high-intensity ultrasonic irradiation under ambien t air for 30 min (temp. raised to 333 K); ppt. was centrifuged after cooling to room temp., washed with water and EtOH and dried in air; X-ray diffraction;
in diethyl ether Irradiation (UV/VIS); precipitation of BiOCl and (after a longer period of time) Bi from an etheric BiCl3 solution during Raman spectroscopy;;
in water byproducts: HClO; addition of Cl2 to aqueous suspension of Bi2O3 under cooling (not above 30°C); formation of BiOCl as intermediate;; precipitation; content of active Cl2: 36 g/l;;
