There are flocculates in ascorbic acid; will this affect the detection of iron ions?

When we analyze iron ions in circulating water, the ascorbic acid used contains flocculates; will this affect the detection of iron ions using a UV-Vis spectrophotometer?

It is recommended to prepare the reagents again, boil deionized water before using it to prepare the reagent solution, and store the resulting solution at low temperature as much as possible. You use this solution to determine total iron as a reducing agent; to ensure efficiency, the reagent needs to remain sufficiently effective. If I’m not mistaken, iron is likely determined using the o-phenanthroline method or the TPTZ method. Additionally, a small amount of preservative that does not affect the measurement can be added to the reagent solution.
