Mechanism on the sorption of heavy metals from binary-solution by a low cost montmorillonite and its desorption potential

Abstract

The increasing global competition within today's manufacturing industries is confronting organizations with interdisciplinary challenges that require intellectual expertise and innovative technological solutions in various knowledge areas. Research organizations and manufacturing companies can improve their overall performance by bundling expertise in collaborative innovation networks. For this purpose a systematic Benchmarking approach has been developed by Fraunhofer IPK to match the competencies and capacities within a pool of organizations in order to facilitate a sustainable cooperation in terms of resources, customers and R&D topics. Furthermore, a KPI-based identification of best performing network-partners allows an initiation of Best-Practice transfers to gain sustainable competitive advantages for the whole network. Based on a methodological approach, the identification of collaboration potentials and Best-Practices is supported by software tools that visualize the results in an understandable and applicable way.

Cadmium Removal from Contaminated Water Using Polyelectrolyte-Coated Industrial Waste Fly Ash

“…R L value gives essential information on sorption nature. R L value for this study as shown in Table 3 indicates a favorable adsorption process ( R L < 1) for 2 mg/L Cd (II) ion concentration [9, 38, 49]. Adsorption of PEFA can also be explained in terms of surface area coverage in contrast to initial concentration of Cd ion [38].…”

“…More active sites resulted in an adsorbent surface and as a result, there was an increase in adsorption capacity. Higher pH values greater than 7.0 are usually avoided in most adsorption studies, due to the possibility of metal precipitation [62]. - [52] As can be seen in Figs.…”

“…5e). It can also be observed that as the concentration of the metal increases, the percent removal decreases which reflects the limited number of adsorption sites in the composite and that at high concentrations, the adsorption sites become saturated 20,21,28 . …”
