i prepared Si doped Hydroxyapatite powder. In that powder, how i will check the Si element?
if i will go for ICP-OES or ICP-AES?
incase i will go ICP_OES or ICP-AES, what are the procedure to make powder into solution?
Hello Gurumoorthi Ramar
I'm not an ICP specialist but if you just want to analyse Si, you have to dissolve your SiHA powder with hydrofluoric acid (be careful). But if you need to quantify Ca at the same time, measurements may be biaised by reaction between Ca and F. You can find sample preparation methods online easily.
Best regards.
The two abbreviations you use are for the same ICP instrumentation.
Etienne's statements about HF are correct, but you might have trouble finding somebody who has an ICP that will handle solutions containing HF. The alternative is colorimetry using molybdate and that works quite well.
Hi,
try a microwave digestion. No more than 0.5g of your sample in 3 ml of HNO3 and check if you have a full digestion if not play with concentrations, temp and ramp time. After that just bring down the HNO3 conc. (dilution). The problem is running the Si in the ICP-OES - silicon is not easy to work with.... good luck.
