Combining pyrohydrolysis and ICP-MS for bromine and iodine determination in airborne particulate matter

“…In this sense, a solution of 50 mmol L −1 NH 4 OH was chosen as absorbing solution for subsequent tests using pyrohydrolysis for the digestion of APM collected on the glass fiber filter. It is important to point out that the use of diluted alkaline solution (50 mmol L −1 NH 4 OH) reduces the memory effect on ICP-MS determination step [60,61].…”
