Phosphates may pose a threat to the aquatic ecosystem when there is a connection or a path between the soil and the aquatic ecosystem. Runoff and drainage ditches connect arable land with the waters of the receiver. Phosphates in the runoff and the ditches contribute to the negative phenomenon of surface water eutrophication. In order to prevent it, certain reactive materials are used which are capable of the selective removal of compounds by way of sorption or precipitation. Zeolites can be distinguished among the many reactive materials. Within the present analysis, the modification of a reactive material containing zeolites was carried out using calcium hydroxide solutions of different concentrations. A certain concentration of calcium hydroxide was created for use in further studies. In order to characterise the new material, an analysis was done of the chemical and mineral composition, as well as the porous texture and morphology. The efficacy of phosphate removal for its typical concentrations in drainage waters in Poland was confirmed by way of an experiment. Using a modified reactive material as an element of landscape structures may reduce the negative impact of phosphates on the quality of surface water.
当土壤与水生生态系统之间存在联系或路径时，磷酸盐可能会对水生生态系统构成威胁。径流和排水渠将耕地与受纳水体连接起来。径流和排水渠中的磷酸盐会导致地表水富营养化这一负面现象。为了防止这种情况，人们使用某些活性材料，这些材料能够通过吸附或沉淀的方式选择性地去除化合物。在众多活性材料中，沸石脱颖而出。在本分析中，使用不同浓度的氢氧化钙溶液对含沸石的活性材料进行了改性。制备了一定浓度的氢氧化钙用于进一步研究。为了表征这种新材料，对其化学和矿物成分以及多孔结构和形态进行了分析。通过实验证实了该材料对波兰排水中典型浓度磷酸盐的去除效果。使用改性活性材料作为景观结构的一个元素，可以减少磷酸盐对地表水水质的负面影响。
