【摘要】 本文提出一种确定萃取反应热力学萃取平衡常数的单参数方程（a＝4.9）,方法简便,用P538萃取疏氰酸钒（Ⅳ）配合物的实验,在较宽的离子强度范围内有良好线性关系,在一般萃取实验条件下,用作图法可求出热力学萃取平衡常数,有普遍意义。更多还原

【Abstract】 This report propose a mono-parameter equation to determine reaction thermodamamic equilibrum constant of extraction easily. The expriment extracting complex [V (SCN )n]4-n with P538 shows fine linear relationship within relative wide scope of ionic activity. It shows universal value to determine thermodynamic equilibrum constant of extraction by description under usual experhoental condition.更多还原
