The synergistic effect of Cu and Mn is listed as follows:(1) On improving the structure of rust layer, addition of Cu and Mn can reduce cracks and pores in rust layer;(2) On altering the composition of rust, it can increase the amount of Fe3O4 and γ-FeOOH, while decrease that of β-FeOOH;(3) On the chemical state of alloying elements and selectivity of rust layer, it mainly convert the anion selectivity to canoed selectivity;(4) On the electrochemical aspect, it can decrease the anode current density and increase the corrosion potential of steel.

Cu、Mn的协同作用主要体现在以下几个方面：在改善锈层结构方面，主要是减少锈层中的裂纹与孔洞，提高锈层与基体的结合强度；在改变锈层组成方面，增加Fe3O4和γ-FeOOH的含量，降低β-FeOOH的含量；在元素化学状态与离子选择性方面，促使锈层由阴离子选择性转变为阳离子选择性，抑制Cl-的渗透；在电化学方面，大幅度降低阳极电流密度，提高钢基体的自腐蚀电位。

The salt effect of biosorption process might be related with the radii of cations and the stability of chelates, maybe also related to the interaction between anions and functional groups which had positive charge.

生物吸附过程的盐效应可能与阳离子的半径以及与配位体所形成的配合物的稳定性有关，也可能与菌体表面带正电荷的官能团与阴离子之间的静电作用有关。
