应用附注/ APPLICATION NOTE
金属离子的选择性是依据进流液的pH 而决定在某些的pH 范围内, 交换容量会很严重的下降.
zyx的除铜pH : 3 - 4
Effective pH for copper removal
zyx的除镍pH : 3 - 5
Effective pH for nickel removal
zyx的除铁pH : 2 - 4
Effective pH for iron removal
zyx的除铅pH : 2 以上
Effective pH for lead removal
zyx的除锰pH : 4 以上
Effective pH for manganese
选择性的顺序如下:
Order of selectivity is as follows
Cu > Pb > Ni > Zn > Co > Cd > Fe+3 > Mn > Mg > Ca >> Na
再生药剂的选择可用盐酸或硫。对于除铜应用, 建议用硫酸! 建议用硷NaOH 再生将树脂转换成Na 型, 并将pH 变成原来的进水条件。
