Effective pH for copper removal

***有效的除镍pH : 3 - 5

Effective pH for nickel removal

***有效的除铁pH : 2 - 4

Effective pH for iron removal

***有效的除铅pH : 2 以上

Effective pH for lead removal

***有效的除锰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。
