Aluminum ferric chloride polymer was originally added as a phosphorus removal agent, but now, after its addition, TP levels not only fail to decrease but actually increase. After this situation occurred, the chemical was sent for testing, and the levels of alumina and total iron were within the specified limits. It is now suspected that phosphates are present in the chemical, but if phosphates are indeed there, they will form complex compounds with polyaluminum ferric chloride, and as a result, it should be impossible to detect the amounts of alumina and total iron. What is puzzling now is whether phosphate can undergo complexation reactions under acidic conditions Or are there any other reasons?
