    Abstract

    We present solvent extraction using a microchannel device for purification of silica, focusing upon boron extraction with 2-ethyl-1,3-hexanediol (EHD). Boron was successfully eliminated from the samples, which consists of silica and boric acid as well as refined diatomaceous earth. The residual boron content after the extraction using a microchannel device was lower than that using a conventional separatory funnel, although the contact reaction period was much shorter. It is suggested microchannel device is an attractive method to produce high-purified silica for solar grade silicon.
