在pH为3.0的0.2 mol/L邻苯二甲酸氢钾-HCI和5.0×10~(-6)mol/L水杨基荧光酮底液中,线性扫描可得灵敏的Ga-SAF络合物吸附波,峰电位为-0.93V(vs SCE).镓在7.5×10~(-9)～3.8×10~(-7)mol/L浓度范围内与峰高成正比关系.
In the 0.2 mol / L potassium hydrogen phthalate-HCl and 5.0 × 10 -6 mol / L salicylfluorone solution at pH 3.0, the linear Ga-SAF complex was obtained by linear scanning The peak potential was -0.93 V (vs SCE), and the gallium concentration was proportional to the peak height in the range of 7.5 × 10 -9 ~ 3.8 × 10 -7 mol / L.
