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

我们已经证明，对高岭土进行简单而廉价的改性可以产生吸附大量铵(N)和磷(P)的材料。我们打算评估和开发这些水处理材料，以减少向河流和湿地的N、P输入。然后，这些材料可以用作化肥。类似地，向沙质土壤中添加这种材料以减少化肥中N、P的淋失也将被研究。这项研究的主要成果将是减少废水和化肥中N、P造成的富营养化的有效和廉价的程序。

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.
