产品详细

SQD-407是-种大孔苯乙烯系砷选择性树脂，可以从含有大量其它阴离子的溶液中选择性吸附砷酸根和亚砷酸根，可以广泛应用于含砷酸根/亚砷酸根饮用水、工业废水的处理。处理后的砷含量可以达到10ppb一下。

SQD -407 is a macroporous polystyrene-based Arsenic selective resin. It selectively adsorbs Arsenate and Arsenite from water and /or waste water containing various other anions. This resin is widely used for the treatments of drinking water and industrial waste water. After the treatment, the Arsenic content in the water could be less then 10ppb.

▲树脂再生方法(Regeneration Method)
SQD-407树脂一般两个柱串联使用以达到较好的处理效果。待出水砷含量超标时，再生一个柱中的树脂。再生分两步进行，先用5-8%的氯化钠溶液淋洗树脂，用量为树脂体积的2倍，1小时通完。然后用2-3倍的清水或去离子水置换。再用2-3倍的2-3% NaOH溶液淋洗树脂，也是1小时通完，最后再用去离子水或清水洗至出水pH8-9即可备下次使用。

SQD-407 resin is usually used in two columns connected in series to get a better Arsenic removal efficiency. When the leakage of Arsenic in the effluent of the second column is over the required limit, the resin in the first column is regenerated. The regeneration is done by two steps.First, passing 2-3BV of 5-8% NaCI through the resin in 1 hour. Then wash with 2-3BV of DI water or clean water. Then Passing 2-3BV of 2-3% NaOH through the resin in 1 hour, and then rinse it with DI water or clean water until the effluent pH 8-9. Then the resin is ready for next run.
