Effective and sustainable separation processes for critical metals, especially the physicochemically similar elements nickel cobalt in battery recycling, are of great interest future. Selective adsorption represents a highly potential process this purpose. In publication, silica adsorbent functionalized with an amino-polycarboxylate derivate (HSU331) was investigated regarding selective Ni(II) presence Co(II) acidic solution (pH range at equilibrium 1.8–2.3) elevated temperature. Comparable...

Haptoglobin (Hp) is one of the acute phase proteins (APP) in blood vertebrates that involved immune responses. Hp concentrations are found to vary under conditions of, for example, infection, trauma or cancer. These variations and changes its constitution frequently used assess health status mammals. In this work, from plasma diseased healthy harbor seals was isolated structurally characterized. The process developed isolation based on glycoprotein enrichment crude samples by means ConA...

Selective separation of heavy metal ions from acidic aqueous solutions is strong interest for certain industrial processes, such as electroplating, well environmental protection, example battery recycling. Amino-functionalized adsorbents are often discussed suitable material this purpose. Herein, two silica-based functionalized with 3-aminopropyl- and 3-[2-[2-aminoethylamino]-ethylamino]-propyl-ligands resulting in MonoA TriA, respectively, were investigated regarding their behavior focus on...

The cnidocysts and the lytic, cyto- neurotoxic potency of a large specimen Cyanea capillata (L.) with 55 cm umbrella diameter were compared those pooled C. sample (average ø 14 cm) in order to investigate organismal developments at cellular biochemical level. Nematocysts type A-isorhiza both fishing tentacles oral arms O-isorhizas enlarged specimen. Additionally, number nematocysts per battery was increased. Increased gill cell toxicity activity demonstrated for tentacle venom comparison...

Abstract Perfluoroalkyl acids (PFAAs) are widespread in the aquatic environment and also measurable ground drinking water. Because of insufficient PFAA elimination conventional water treatment processes, e. g. active carbon based methods, consumers areas with contaminated supplies exposed to an elevated health hazard. For this purpose, applicability five differentially fluorinated silica-based adsorbents (HSU00107954-958) remove potentially human toxic perfluoroalkyl sulfonic acids(PFSAs)...
