Di-(2-ethylhexyl)-phosphoric acid(D2EHPA), tributyl phosphate(TBP)와 carbon nanotube(CNT)를 고정화한 polysulfone(PSf) 복합체를 제조하여 수중의 Sr(II)을 제거하는데 사용하였다. 주사전자현미경(SEM)과 적외선 분광기(FTIR)를 사용하여 제조한 PSf/D2EHPA/TBP/CNT 복합체의 특성분석을 하였다. 그리고 PSf/D2EHPA/TBP/CNT 복합체에 의한 Sr(II)을 제거하는 경우에 60 min에 평형에 도달하였다.
Polysulfone (PSf) composite immobilized with di-(2-ethylhexyl)-phosphoric acid (D2EHPA), tributyl phosphate (TBP) and carbon nanotube (CNT) was prepared and used for the removal of Sr(II) from aqueous solution. The prepared PSf/D2EHPA/TBP/CNT composite was characterized by scanning electron microscopy (SEM) and fourier transform infrared spectrometer(FTIR). The equilibrium time of the Sr(II) by PSf/D2EHPA/TBP/CNT composite was 60 min.
