If acidic leaching was deployed to enhance removal of tank waste residues, the resulting acidic Al(NO3)3 leachate solution could contain measurable amounts of solubilized transuranic elements and so would demand treatment prior to disposal. In this study, a liquid‐liquid extraction system for the ...
DFT, Monte Carlo and molecular dynamics simulations for the prediction of corrosion inhibition efficiency of novel pyrazolylnucleosides on Cu(111) surface in acidic media Article Open access 12 February 2021 Data availability All data generated or analyzed during this study are included in this publ...
The removal of chromium (Cr) from wastewater by various adsorbents has been investigated. As compared with the commercial activated carbon, the biosorbents with inexpensive and high adsorption capacities are developed from lignocellulosic wastes. Lignin,
Results show that the initial solution pH plays a crucial role in the morphology of the final γ-AlOOH products: the acidic conditions are favored toward the formation of nanorods and the basic conditions toward the formation of nanoflakes. The one dimensional growth of γ-AlOOH nanorods was ...

The conventional solutions, prepared in the literature using NTA, NH4OH, MoO3and Co(NO3)2, (here DISAMON method), were neutral or basic. The solid obtained by their drying was partly crystalline. The DISUSPEN solutions were acidic, with pH=1.0–1.5. The DISUSPEN solids were XRD-amorphous ...
Molecular Structure and Spatial Orientation of the Intercalated Cetirizine Figure 2A shows the three ionizable forms of cetirizine; a strong acidic group with pK2 = 2.9, a strong basic group with pK3 = 8.0 and a very weakly basic group with pK1 = 2.2 [19]. According to XRD analysis, the...
Figure 14C shows a change in the surface charge of the alumina treated at 1600 ◦C from positive to negative at acidic pH, while at basic pH, the negativity increases, crossing the isoelectric point at a pH lower than 2. The positive surface in alumina is due to the presence of ...
After drying, the residue is dissolved in acetone (10 mL) and eluted through a column of acidic aluminum oxide with acetone. The yellow or tawny fraction is collected and evaporated under reduced pressure. The solid residue is crystallized from an appropriate solvent or purified by silica gel ...
