Under certain conditions, for afeed solution with Cu2+ concentration of 50mg/L, EDI was able to produce a purewater product containing non-detectable concentrations of Cu2+. Dilute resistivity ofthe EDI process was in the range of 2.2-5.6 MΩ.
在一定的操作条件下,对于 Cu2+离子浓度为50mg/L 的原料水,通过 EDI 处理后,其产出淡水电阻率可达 2.2-5.6 MΩ.
This paper determined the solubility of Sodium Hexafluoroantimonate at 308 K with the equilibrium method,and the concentration of Sodium Fluorine and Hydrogen Fluorine were studied to determine their influence on the solubility of Sodium Hexafluoroantimonate.
Result showed that titanium dioxide with 11.30 nm of diameter was obtained when the concentration of reactant was 1.2 mol/L with pH 3,and reaction at 70 ℃ for 3 h at 600 r/min,and then calcination for 3 h. The particles were symmetrical and well-dispersed.
As the increase in the concentration of trichloroisocyanuric acid,CaCO3 scale inhibition efficiency of HEDP,PBTCA and HPAA increases firstly but decreases afterward,and CaCO3 scale inhibition efficiency of PAPEMP decreases continuously.
