precipitation yield
The precipitation yield is unaffected by temperature.
      
Results obtained indicate that variations of HF concentration do not influence the K2TaF7 precipitation yield, but variations in KF concentration do.
      
The precipitation yield of Cs-TFPB is 99.1±0.3% in the pH range from 0.7 to 10.8 Rb-TFPB is rather soluble in aqueous solution and its solubility products are determined to be 1.6×10-5 mol2·dm-6 at 0°C.
      
In any case, results indicate very large incorporation yields of57Co in the precipitate, independently from the intrinsic precipitation yield of the host compound.
      
In a Pd solution of 0.5M and 2M HNO3, the precipitation yield of Pd increased with hydrazine concentration and reached over 98% at 0.1M.
      
The precipitation yield of Pd at 0.5M HNO3 was higher than at 2M HNO3.
      
In these cases, the problem is how to increase the precipitation yield of target element and to prevent impurities from coprecipitation.
      
The effects of concentrations of oxalic acid and ascorbic acid on the precipitation yield and purity of uranium were observed.
      
The dependence of precipitation yield, mean crystal size and particle size distribution on rotation speed, axial flow rate and initial supersaturation ratio has been studied.
      
A leachability as low as 0.5 mg/L As at pH 5 and 22 °C (TCLP-like test) is obtained when the initial molar ratio Fe(III):As(V) is increased to 3:1, but the precipitation yield is very low.
      
The effect of concentrations of oxalic acid and nitric acid in the simulated waste on the precipitation yield and purity of Nd and Am was examined in this study.
      
The precipitation yield of Pd by ascorbic acid decreased with the increase of the nitric acid concentration.
