产品详细

D406是一种大孔苯乙烯系氟选择性螯合树脂，可以从含有大量其它阴离子的溶液中选择性吸附氟离子，处理后的氟离子含量可以达到1mg/L 以下。可以广泛应用于含氟饮用水和废水的处理。

D406 is a macroporous polystyrene-based Fluoride selective chelating resin. It selectively adsorbs Fluoride from water and /or water solutions containing various other anions. The Fluoride content of the treated water could be lower then 1mg/L. This resin is widely used for the treatments of drinking water and waste water containing Fluoride.

▲树脂再生方法(Regeneration Method)
D406树脂可以单柱使用也可以两柱串联使用，对于氟含量高的工业废水，建议采用后者。待出水氟含量超标时，再生(第一柱)树脂。再生剂为浓度5%的硫酸铝，用量为树脂体积的2-3倍，从上到下通，1-1.5 小时通完。然后用清水洗至出水用铝试剂检测无铝即可。备下次使用。

D406 resin can be used in only one column or in two columns connected in series. For the industrial waste water containing high Fluoride content, the later is suggested. When the Fluoride in the effluent exceeds the requirement, the resin (in the first column) is regenerated. The regenerant is 5% Aluminum Sulfate. The amount is 2-3 times the volume of the resin, from top to bottom, passing through in 1-1.5 hours. Then wash with clean water to that no Aluminum is detected by Aluminon in the effluent. Then the resin is ready for next run.
