摘要: This paper aims to examine the potential of permeable reactive barriers (PRBs) as an in-situ removal approach for phosphate polluted agricultural runoff. Four different materials (RMs) of: autoclaved aerated concrete (AAC), Polonite®, zeolite and limestone were tested. The study was conducted a column experiment with sandy loam soil type charging underlying RM layers phosphorus (P) without reference. carried out over 90 days. During this time P-PO4 load from reference equaled 6.393 mg corresponds 3.87 kg/ha. Tested RMs are characterized by high retention equaling 99, 98, 88 65% AAC, limestone, respectively. At common annual P loss rates 1 kg/ha intensively used soils, PRB volume ranged 48 67 m3 would reduce between 65 99% tested in study.
