“…A large amount of wastewater containing Pb 2+ is inevitably produced from non-ferrous metal mining and smelting [1][2][3], lead-acid batteries [4,5] and other chemical production processes [6]. Because of its non-degradability and the enrichment in natural circulation systems Pb 2+ may cause serious harm to humans, animals and plants [7,8]. Therefore, the effective treatment of wastewater containing lead is an important and urgent issue for ecological security and the environment.…”

In order to effectively realize the removal of low concentrations of lead ions in wastewater via capacitive deionization technology, MnO2 composite electrodes were prepared by a galvanostatic co-deposition approach, where polyaniline (PANI) and graphene were added to an MnO2 deposition solution and nickel foam was chosen as the substrate of the electrode. The microstructure, capacitance characteristics and adsorption behavior of Pb2+ ions of the electrodes were analyzed by scanning electron microscopy, X-ray diffraction, X ray photoelectron spectroscopy, laser Raman spectroscopy, cyclic voltammetry and capacitance deionization processes. The experimental results showed that the MnO2-PANI-graphene composite electrode has a high specific capacitance (132.8 F/g) and a 61.8% removal rate for simulated wastewater containing 20 mg/L Pb2 + ions under the conditions of 30�C and 1 mA/cm2, with the addition of 1 g/L PANI and 3 g/L graphene, respectively. Electroadsorption process was in accordance with the Lagergren quasi-second-order kinetic equation. The co-deposition of PANI and graphene oxide could play obvious role in enhancing the adsorption capacity and stability of the electrodes.

Mycotoxins are agents with different and complex chemical structures, with toxic effects for humans and animals. They can be present in feed and food, although in very small quantities, mycotoxins have a negative effect on the health of animals and people. Ochratoxins are mycotoxins intensively studied in recent years due to their toxicity on the animal and human body; these toxins show nephrotoxic, immunotoxic and myelotoxic, neurotoxic and carcinogenic effects. Thirty male rats of the Sprague- Dawley breed were divided into 3 groups who received through feed doses of of ochratoxin A (OTA): 0.5 mg OTA/kg BW, 1 mg OTA/kg BW and non OTA (control group). The blood samples collected on the anticoagulant were subjected to the analysis of the main components: hemoleucogram and biochemical parameters. The variations of the determined biochemical parameters (alanine aminotransferase, aspartat aminotransferase, serum creatinin, serum urea and blood urea nitrogen) indicate changes in the kidney and liver function in the animals from the experimental groups compared to the control group. The parameters of the hemoleucogram count also register variations depending on the administered dose of OTA.
