Hello everyone,
I have a question regarding the As speciation in root iron plaque. Based on my reading DCB extraction is a well-known method however, it is an alkaline medium and I am facing problems to use ICP-MS and ICP-OES that runs on acidic digestion which will lead to dilution problems.
Is there a modified DCB extraction method that is compatible with ICP-MS/ICP-OES? Or is there a method where root iron plaque is digested in an acidic solution for As speciation measurement?
Also, I am not sure if my country has an X-ray absorption spectroscopy that is usually used to identify As species in iron plaque.
Hi there, to those of you following the question. I have done some reading and there was one paper that conducted As speciation in root iron plaque using a different method of extraction. Briefly, it's called the sodium acetate-sodium citrate and ascorbic acid digestion method which is compatible with the ICP instrument. Thank you all. I have attached the reference material for your reading.
Simply you can refer to HPLC to determine the exact speciation of As in root tissues. In my opinion this method is more accurate than synchrotron based techniques.
