As shown in Fig. 2 A, the removal rates of Cu 2+, Zn 2+ and Pb 2+ ions increased rapidly in the first few minutes and then increased slightly. The removal rate of Pb 2+ was the highest, reaching nearly 100 % after 10 min. The final removal rates of Cu 2+ and Zn 2+ reached 83.7 % and 52.5 % respectively. In addition, the removal capacity of …

The results show that the maximum adsorption capacities of AA-SW-AMPS for Pb(II), Cu(II), and Zn(II) were 253.49 mg/g, 237.29 mg/g, and 232.15 mg/g, respectively, and the adsorption mechanism is monolayer chemisorption. The adsorbent showed great potential in removing heavy metals from wastewater.
The relation between reaction time and the adsorption of Zn(II), Pb(II) and Cu(II) at pH = 5.0 is shown in Fig. 2b,d. The reaction rate and adsorption capacity for Pb(II) were higher than those ...
Samples of RG, SF and ACB supplied by the companies Tioxide Europe S.A., Azucarera Ebro S.A. and ENCE S.A. respectively, were dried at 45 °C (RG) and 105 °C (SF and ACB) and processed by acid digestion and alkaline fusion [21].The resulting standard solutions were analyzed for major and trace elements by ICP-OES, ICP-MS …
Disc Filters offer an effective solution for pre-filtration in water treatment systems. These filters work by trapping and removing sand and other coarse particles from water, …
Each feature necessitates a time-consuming scan of all samples to determine the estimated information gain of all split points. To address this problem, a light gradient boosting machine (LightGBM) algorithm was introduced here. It was applied to construct a Pb–Zn prospectivity model for the Varcheh district, west of Iran.
The aim of this study was to model the sorption and retention of Cd, Cu, Ni, Pb and Zn in soils. To that extent, the sorption and retention of these metals were studied and the soil characterization was performed separately. ... The computational cost implied both in the estimation process – it is necessary to solve iteratively a quadratic ...
The material cost for a 13 mm diameter 25% PE GDE is estimated to be €0.0324 per electrode (€0.0244/cm 2), which is very cost-effective when compared to, for example, carbon fiber paper 9 with ...
As mentioned, the advantages of the ASP method include its low cost and easy operation. The most expensive one-time cost is the laser engraving machine.
The sediment background values of Zn, Pb, and Cu in Bohai Bay are 57 mg/kg, 11.5 mg/kg, and 19 mg/kg, respectively [41,42], and the concentration of the three metals are distinctly above the environment background values, particularly Zn, indicating the current severe pollution status of marine sediment in Bohai Bay.
The analytical procedure for the determination of Fe, Mn, Zn, Cu, Cd, As, Pb and Se in water in concentrations as low as a few ppM involves precipitation with a carrier of the metals by ...
