A millimeter-scale investigation is key to the understanding of the competitive effects of phosphate(P) on arsenic(As) mobility in sediments by taking the great biogeochemical heterogeneity of the sediments into consideration. In this study, a microcosm experiment was performed in this aspect using high-resolution dialysis and diffusive gradients in thin films (DGT) to simultaneously measure dissolved...
The confinement of air‐protected metallic magnetic nanoparticles in the inner cavity of carbon nanotubes (CNTs) should offer an interesting perspective for biomedical applications or for controlling CNT alignment in composites. Because the direct confinement of polymer‐precoated nanoparticles in CNTs could be restricted by diffusion limitations, we developed a process based on: 1) the confinement...
The paper studied the effect of different solid-liquid ratio, pH, temperature, stirring time and the size of light-burned magnesium on copper effluent concentration, when light-burned magnesium treats simulated copper wastewater 50mg/L combined with chitosan. The results show that: considering economic costs and the actual operability, when the experiment conditions with light burned magnesium-chitosan...
This paper researched on simulated mine water treated with fly ash modified by Na2CO3. The ratio of fly ash and sodium carbonate solution is 1g∶10mL, stirred, dried, crushed and screened. The main chemical components analyzed with GENESIS XM260SX- EDS. The experimental mine water is prepared with AR FeCl3 · 6H2O, MnSO4 · H2O, HCl and deionized water, based on the actual range of mine water quality...
