, internal solution, concentration of SO42–, and acidity in test solution. The best performance was obtained using the membrane with PVC:DBP:HDEHP:HEH/EHP:OA mass ratio of 75:175:5:5:5. The proposed... response within the SO42– concentration range of 0.1–1 mol/L and the acidity range of 0.25–1.2 mol/L H+. The proposed electrode showed high selectivity for Ce(Ⅳ) over a wide variety of interfering ions......

-liquid extraction, which can be expressed as a quasi-first-order reaction. The effect of acidity in aqueous phase, concentrations of extractant, Nd3+ and Sm3+ on extraction rate were discussed......
parameters fixed as constants. The results show that increasing residual acidity can improve leaching rate of indium. Increasing the oxidant content can obviously increase leaching rate but the further..., thus the BPNN model has a high prediction precision. At last, optimized technical parameters which can yield high leaching rate of 99.5% were obtained by experimental and BPNN studies: residual acidity......
,respectively.Nonpolar solvent and low acidity could improve the extracting efficiency,and successfully strip palladium(Ⅱ)from the loaded organic phase was achieved with 0.5 mol·L-1(NH2)2CS solution.It was proposed......
on the physical properties, such as particle size, were investigated. It is found that the particle size of the powder is controllable by adjusting acidity in bottom water and charging rate. The powder......

during degradation duration of 12 weeks. The results reveal that the acidity of PDLLA degradation products was weakened or neutralized by grafting butanediamine onto PDLLA. A uniform degradation of BDPLAs was observed in comparison with an acidity-induced auto-accelerating degradation featured by PDLLA and MPLAs. The biodegradation behaviors of BDPLAs can be adjusted by controlling the content......
