Abstract	Abstract This research investigated the effects of various nutrients on arsenic (As) removal by arsenic hyperaccumulator Pteris vittata L. in a Hoagland nutrient solution (HNS). The treatments included different concentrations of Ca and K in 20% strength of HNS, different strengths of HNS (10, 20 and 30%), different strengths of HNS (10 and 20%) with and without CaCO 3 , and different concentrations of Ca, K, NO 3 , NH 4 , and P in 20% strength of HNS. The plants were grown in nutrient solution containing 1 mg As L −1 for 4 weeks except the Ca/K experiment where the plants were grown in nutrient solution containing 10 or 50 mg As L −1 for 1 week. Adding up to 4 mM Ca or 3 mM K to 20% strength HNS significantly ( P −1 . Plant arsenic removal was reduced with increasing Ca and K concentrations at 50 mg As L −1 . Lower strength of HNS (10%) resulted in the greatest plant arsenic removal (79%) due to lower competition of P with As for plant uptake. Addition of CaCO 3 to 20% strength of HNS significantly increased arsenic removal by P. vittata . Among the nutrients tested, NO 3 and CaCO 3 were beneficial to plant arsenic removal while NH 4 , P and Cl had adverse effects. This experiment demonstrated that it is possible to optimize plant arsenic removal by adjusting nutrients in the growth medium.
