Capturing of heavy metal ions by using HNT/EDTMP nanocomposite |
| 초록 |
Halloysites have been newly modified with ethylenediaminetetrakis- (methylenephosphonic acid) (EDTMP) on its surface. Phosphonic acid functional group of EDTMP would make strong bidentate and tridentate bond on the halloysite surface. This hybrid material can be easily bound to heavy metal ions. Metal ions chelated on halloysite/EDTMP nanocomposites had specific color changes depend on the kinds of the metal ions. 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. This would be compared to the heavy metal ions adsorption ability of unmodified halloysite to prove the enhancement of heavy metal ions adsorption by EDTMP modification. |
