Dust grain surface potential in multi-ion plasmas having two negative ions within the context of kappa-distributed dusty plasma is studied analytically and numerically. The plasmas current equations ${\mathit{Xe}}^{+}-F^{-}-{\mathit{SF}}_6^{-}$ and ${\mathit{Ar}}^{+}-F^{-}-{\mathit{SF}}_6^{-}$ solved using the typical parameters of laboratory multi-ion plasmas and attained dust grain surface potential strongly depends on the plasma parameters for example kappa, density, and temperature ratios. The dust grain surface potential displays the non-monotonic behavior for values of the kappa, temperature ratio and for changed values of density ratios in the framework of both ${\mathit{Xe}}^{+}-F^{-}-{\mathit{SF}}_6^{-}$ and ${\mathit{Ar}}^{+}-F^{-}-{\mathit{SF}}_6^{-}$ plasmas. Additionally, the temperature ratio effect is minor on the dust grain surface potential. Our results show that considering the broad variety of ${\mathit{Xe}}^{+}-F^{-}-{\mathit{SF}}_6^{-}$ and ${\mathit{Ar}}^{+}-F^{-}-{\mathit{SF}}_6^{-}$ masses is of great importance and advantageous for the analyses of plasma physics, particularly the physics of multicomponent plasmas.

在kappa分布的粉尘等离子体的背景下，对具有两个负离子的多离子等离子体中的粉尘颗粒表面电势进行了分析和数值研究。等离子体电流方程${\mathit{e}}^{+}--F^{--}--{\mathit{SF}}_6^{--}$ 和 ${\mathit{氩气}}^{+}--F^{--}--{\mathit{SF}}_6^{--}$使用实验室多离子等离子体的典型参数求解和获得的尘埃颗粒表面电势在很大程度上取决于等离子体参数，例如κ，密度和温度比。尘埃颗粒表面电势在k和k值，温度比以及密度比的变化值都显示非单调行为的情况下，两者均显示出非单调性。${\mathit{e}}^{+}--F^{--}--{\mathit{SF}}_6^{--}$ 和 ${\mathit{氩气}}^{+}--F^{--}--{\mathit{SF}}_6^{--}$血浆。另外，温度比对粉尘颗粒表面电势的影响很小。我们的结果表明，考虑到${\mathit{e}}^{+}--F^{--}--{\mathit{SF}}_6^{--}$ 和 ${\mathit{氩气}}^{+}--F^{--}--{\mathit{SF}}_6^{--}$ 质量对于等离子体物理特别是多组分等离子体的物理分析具有重要意义和优势。
