文摘The FT-IR difference spectroscopy and the Raman spectroscopy were used to ide ntify the polyborate ions in saturated aqueous solutions during dissolution and transformation of 2MgO·2B2O3·MgCl2·14H2O in different HCl solutions at 30℃. The assignments of the recorded IR-Spectroscopic frequencies and Raman shift of the borate aqueous solution are given.
