Product Description:

Oxalic acid is a kind of dicarboxylic acid. It widely exists in the plant kingdom. It has different functions in different fields. In medicine, printing and dyeing, plastics and other industrial production, oxalic acid can  be  used  as  pharmaceutical  raw  materials,  complexing  agents,  bleaching  agents,  precipitants  and reducing agents. From the perspective of food, long-term consumption of vegetables with high oxalic acid content is easy to cause arthritis, low blood calcium, bladder stones, kidney stones and other diseases. Therefore, it is considered to be an antagonist of mineral elements.

 

Fe3+ can form purple complex with sulfosalicylic acid at pH is 2. It has a characteristic absorption peak at 510 nm. Fe3+  and sulfosalicylic acid can produce a purple complex. Oxalic acid and oxalate can make it lighter. At the  same time, the absorbance of Fe3+  and  sulfosalicylic acid complex decreases with the increase of oxalic acid. Accordingly, the content of oxalic acid in the sample can be
