Research Paper (postgraduate) from the year 2016 in the subject Environmental Sciences, grade: 9.00, , language: English, abstract: In this study, Taguchi L27 experimental design was utilized to optimize adsorption of Reactive Orange 12 (RO 12) dye onto magnetic manganese oxide and manganese ferrite (MO-MnF) nanocomposite. The MO-MnF nanocomposite was characterized by X-ray diffraction (XRD), scanning electron microscopic (SEM), Fourier transform infrared spectroscopy (FT-IR), and vibrating sample magnetometer (VSM) measurements.The experimental design was constructed with five factors (solution pH, RO 12 dye concentration, MO-MnF dose, contact time, and reaction temperature) at three different levels. The experimental conditions were optimized to maximize the RO 12 dye removal efficiency where signal-to-noise (S/N) ratio was considered as criteria. Optimum values of 2.0, 1.0 g/L, 60 min, 50 mg/L and 60°C were obtained for solution pH, MO-MnF dose, contact time, concentration of RO 12 dye, and reaction temperature, respectively for maximum RO 12 dye removal efficiency of 99.32%. This adsorption process proficiently followed pseudo-second-order and intra-particle diffusion models and exhibited applicability of Langmuir monolayer adsorption with maximum adsorption capacity of 207.90 mg/g at room temperature.

EU Gewährleistungssiegel

Die EU führt ein verpflichtendes, einheitliches EU-Label zur Information über die gesetzliche Gewährleistung ein, ergänzt durch ein Garantielabel, sofern eine freiwillige Herstellergarantie besteht.

Ziel der neuen Regelung ist es, Verbraucherrechte transparenter darzustellen und europaweit einheitliche Informationsstandards zu schaffen. Verbraucher sollen auf einen Blick erkennen können, welche gesetzlichen Mindeststandards gelten, unabhängig davon, in welchem Land oder bei welchem Händler sie einkaufen.

EU Warranty Label

The European Union is introducing a mandatory, standardized EU label to provide information about consumers’ statutory warranty rights. This will be complemented by a guarantee label where a voluntary manufacturer’s guarantee is offered.

The purpose of this new regulation is to make consumer rights more transparent and to establish consistent information standards across the European Union. Consumers should be able to see at a glance which statutory minimum protections apply, regardless of the country or retailer from which they make a purchase.
