| Abstract |
Halloysite/EDTMP, which is made of condensation reaction of alumina and phosphonic acid, has been newly synthesized . The P-O-Al linkage of halloysite surface is probable by covalent bond of alumina and phosphonic acid, which makes strong bidentate and tridentate bond. The remained phosphonic acid parts of EDTMP could easily bind to plus charged ions in the solution. This enables reaction of metal ions and reactive reagents, which is also known as chelating, would be helpful to collect heavy metal ions in solutions. The hybrids would be characterized by means of scanning electron microscopy and IR spectrometry. IR spectroscopy would be for proving bidentate or tridentate P-O-Al linkage of HNT/EDTMP, and chelating bonds of EDTMP and metal ions. An enhanced capacity for adsorption of the modified halloysite toward hydrophilic heavy metal ions would be also shown. |
