硼变色酸络合物形成的结果及讨论。缓冲溶液的pH值和浓度的影响。用醋酸盐缓冲溶液考察了pH对硼络合物形成的影响。在pH为4~5的范围内，峰高和峰面积几乎不变。考察了醋酸盐缓冲液(pH 4.8)的浓度。峰高和峰面积在0.01~0.3m范围内基本不变。
RESULTS AND DISCUSSION Formation of Boron-Chromotropic Acid Complex. Effect of pH and concentration of buffersolution. The effect of pH on the formation of boron complex was examined by using acetate buffer. The peak height and area were almost constant at pH region from 4 to 5. The concentration of acetate buffer (pH 4.8) was examined. The peak height and area were almost constant from 0.01 M to 0.3 M.
