I have attached Bi metal to polymer and i want to analyse it for Bi and P through ICP-OES but the complexes are not digested in conc. HNO3, I dont have access to MW acid digester or LA-ICPMS, what do you suggest in this case?
Make 15 mL aqua regia solution HCl:HNO3 (1:3) and then add 5 ML in three slot. adding 5 mL aqua regia and evaporate all solution by heating at 80 degree celcius. And if small amount left undissolved then pass the solution from syringe filter u will get clear solution.
But if slight was not dissolved then only, either u will not get perfect result.
