摘要
制备了 Mg O· 2 B2 O3-H2 O,Na2 O· 5B2 O3-H2 O和 Mg O· 3B2 O3-H2 O的过饱和水溶液 .采用激光喇曼光谱研究了这些过饱和水溶液 ,并对光谱频率进行了归属 .讨论了过饱和水溶液中硼氧配阴离子的存在形式和相互作用机理 .
Supersaturated aqueous solution of MgO·2B_2O_3-H_2O, Na_2O·5B_2O_3-H_2O and MgO·3B_2O_3-H_2O were prepared. Raman spectra of the solutions have been obtained. The results show that there exist various polyborate anions in the supersaturated aqueous solutions. The assignments of the recorded frequencies of the borate aqueous solution were given. The interaction mechanism between polyborate ions in supersaturated solution was discussed.
