Abstract Batch tests were conducted to study the effects of various organic substances on ferric ion-dependent phosphorus removal, and to reveal their mechanism. The results showed that the influencing strength of chosen organic substances was in the order of citric acid, fulvic acid, polysorbate-80, bovine serum albumin, glucose and starch. The influence of citric acid was 5 times to 20 times higher than that of the other five organic substance. Compared with organic substances containing hydroxyl, organic substances containing carboxyl had more negative effects on the removal of ferric ion-dependent phosphorus. Tests showed that the HFO was the main intermediate product to react with phosphate when ferric iron was used to remove phosphate. Organic substances with carboxyl, such as citric acid, competed with phosphate to bind to the HFO, which resulted in less combination of phosphate to HFO and decrease of phosphate removal. Among all tests, the biggest decrease of phosphorus removal caused by citric acid reached 90.70%.
