應(yīng)用附注/ APPLICATION NOTE

金屬離子的選擇性是依據(jù)進(jìn)流液的pH 而決定在某些的pH 范圍內(nèi), 交換容量會(huì)很嚴(yán)重的下降.

最有效的除銅pH : 3 - 4
Effective pH for copper removal
最有效的除鎳pH : 3 - 5
Effective pH for nickel removal
最有效的除鐵pH : 2 - 4
Effective pH for iron removal
最有效的除鉛pH : 2 以上
Effective pH for lead removal
最有效的除錳pH : 4 以上
Effective pH for manganese
選擇性的順序如下:
Order of selectivity is as follows
Cu > Pb > Ni > Zn > Co > Cd > Fe+3 > Mn > Mg > Ca >> Na
再生藥劑的選擇可用鹽酸或硫。對(duì)于除銅應(yīng)用, 建議用硫酸! 建議用鹼NaOH 再生將樹脂轉(zhuǎn)換成Na 型, 并將pH 變成原來的進(jìn)水條件。
