Cerium(IV) sulphate (0 1m). Dissolve 40 4 g of cerium(IV) sulphate tetrahydrate, Ce(S04)2.4H20, or 63 6g cerium(IV) diammonium sulphate dihydrate, Ce(S04)2.2(NH4)2S04.2H20, in a cold mixture of 500 ml water and 50 ml concentrated sulphuric acid, and dilute the solution with water to 1 litre. 

Martin-Gil et al. reported on the synthesis of cubic carbon nitride with the zinc blende structure by pyrolysis of N,N-diethyl-l,4-phenylene-diammonium sulphate at 800°C in an N2 atmosphere using Se02 as a catalyst [90]. The material obtained contained both an amorphous matrix and polycrystalline regions with crystallites of 5-50 nm in size. The sample as whole had a composition with 0.2 estimated using EELS (electron energy loss spectroscopy) data to be C N, with x and y between 3 and 4. The... 

Zirconium ( > 100 mg in ca /. M sulphuric acid solution). Add freshly prepared 10 per cent aqueous diammonium hydrogenphosphate solution in 50-100-fold excess. Dilute to 300 mL, boil for a few minutes, allow to digest on a water bath for 15-30 minutes and cool to about 60 °C. Filter through a quantitative filter paper, wash first with 150 mL of 1M sulphuric acid containing 2.5 g diammonium hydrogenphosphate and then with cold 5 per cent ammonium nitrate solution until the filtrate is sulphate-free. Dry the filter paper and precipitate at 110°C, place in a platinum crucible and carefully burn off the filter paper. Finally heat at 1000 °C for 1-3 hours and weigh as ZrP207 (Section 11.51).

In an attempt to remove the problems associated with the acetone coagulation bath, fibers were air-gap spun into aqueous salt solutions, eg up to 25% of diammonium hydrogen phosphate or potassium phosphate or 5% zinc sulphate (109). This patent also makes it clear that the corrosive nature of the solution is an issue in spinneret design.
