An evaluation of novel aluminosilicate materials based on modified kaolins for environmental applications

我们已经表明，高岭土的简单和廉价的改性产生吸附大量铵（N）和磷酸盐（P）的材料。我们打算评估和开发这些材料用于水处理，以减少N，P输入到河流和湿地。这些材料可以用作肥料。同样，还将研究向桑迪土壤中添加这些材料以减少肥料中N、P的沥滤损失。这项研究的主要成果将是有效和廉价的程序，减少富营养化由于N，P从废水和肥料。

We have shown that simple and inexpensive modification of kaolin produces materials that adsorb large amounts of ammonium (N) and phosphate (P). We intend to evaluate and develop these materials for water treatment, so as to reduce N, P inputs into rivers and wetlands. The materials can then be used as fertilisers. Similarly addition of the materials to sandy soils to reduce leaching losses of N, P from fertilisers will be investigated. The major outcome of this research will be effective and inexpensive procedures for reducing eutrophication due to N, P from waste water and fertilisers.
