ポリビニルアルコールのネットワーク構造を利用したジオポリマー粉末の調製

Abstract

We developed geopolymer powders using network-structure of polyvinyl alcohol for the use of water purification at developing region. Geopolymer powders with different diameter were obtained by different condition such as PVA concentration, the ratio of geopolymer precursor to PVA solution and drying procedure. Prepared geopolymer powders were characterized with X-ray diffraction and laser diffraction particle size analyzer. The lead removal ability of geopolymer powder was investigated using inductively coupled plasma atomic emission spectroscopy. Geopolymer powder with small median diameter tend to easier to remove lead compared with geopolymer prepared using well known method.
