Zero - valence iron process treatment of landfill leachate

零 价 铁法处理垃圾填埋场渗滤液

The results of XPS show that palladium was almost in zero valence state .

XPS结果表明，钯几乎全部以 零 价 态 存在。

At temperatures below 110 ℃ the sticking coefficient for In atoms is close to zero due to saturation of valence bonds resulting from the arrangement of In atoms in the 4 × 1-In overlayer .

在110℃以下，几乎为 零的铟原子的粘着系数是由于4×1-In结构的原子排列使表面呈现 价键饱和状态所致；

The result of XPS showed that the valence state of Pt existed on the electrodes was zero valence and there was a small quantity of thiol on the electrode .

结果表明，自组法制备载铂电极表面的铂催化剂是以 零 价 态即金属铂的形似存在的；低温制备电极的表面尚有微量的硫醇有机物存在。
