[0013] two. Medicines and reagents
[0014] NaOH: analytically pure
[0015] Hydrochloric acid: 10% analytical grade
[0016] Ammonia: 10% analytical pure
[0017] Buffer solution: NH per liter 4 Ac16.6g, NaAc36.2g
[0018] Mixed masking agent: aqueous solution, containing 10% glycerin, 2% disodium EDTA, 1% sodium oxalate
[0019] Standard solution: commercially available, the diluent contains 10μg of beryllium per ml for use.
[0020] 3. Measurement steps
[0021] Weigh 1.0000g sample in a silver crucible, add about 8g NaOH, melt it in a muffle furnace at 750℃ for about 20 minutes, take it out and cool it, put the crucible together with the melt in a 150ML beaker containing 100mL of pure water, and use it ...
