  • PPCPs: Preparing for an uncertain regulatory future

    A recent study published in Environmental Pollution* identified 56 active pharmaceutical ingredients (APIs) in effluent samples from 50 large wastewater treatment plants across the U.S. Among the products found in samples were commonly prescribed anti-psychotic and antihypertensive drugs. As more studies continue to fuel public concerns over risks to public health and the environment, wastewater ...

  • Shellfisheries: Time to prepare for ocean acidification

    Both physical and social factors must be considered as coastal communities brace for an uncertain future. Oceans are gradually becoming warmer and more acidic as more carbon dioxide enters the atmosphere — two shifts that are altering the economic foundations of many coastal regions. In a ...

  • Sweeter smelling solution at grampian prepared meats

    Chicken blood was previously drawn from the collection sump in the production area, via a vacuum pump, to fill a pressure vessel. This blood was then transferred into a 30 tonne holding tank by a blower and the necessaryventing of this system to atmosphere gave rise to the odour and required addressing ahead of the 2007 cut-offdate for compliance with the latest regulations. Mono’s solution was ...

  • Degradation of Amaranth azo dye in water by heterogeneous photo-Fenton process using FeWO4 catalyst prepared by microwave irradiation

    FeWO4 particles were synthesized by a simple, rapid and facile microwave technique and their catalytic properties in heterogeneous photo-Fenton reaction were evaluated. This material was employed in the degradation of Amaranth azo dye. Individual and interactive effects of operational parameters such as pH, dye concentration and H2O2 dosage on the decolorization efficiency of ...

  • Preparation of a fouling-resistant sustainable cathode for a single-chambered microbial fuel cell

    Two different binder materials of varying water affinity, viz. poly vinyl alcohol (PVA) and poly-tetrafluoroethylene (PTFE), and biocide vanillin were tested for cathode fouling in a single chamber air-cathode microbial fuel cell (MFC) constructed with a low-cost baked clayware cylinder and operated under fed-batch mode. PVA and PTFE loadings of 0.5 mg/cm2 were used for MFC-1 and MFC-2, ...

  • Effects of current density on copper nanoparticle prepared by electrochemical method

    Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...

  • Preparation of xanthated bentonite and its removal behavior for Pb(II) ions

    Xanthate was successfully grafted onto bentonite by a relatively simple solution reaction. The obtained xanthated bentonite (XBent) was characterized by FT-IR spectrophotometer, thermogravimetric analysis (TG), particle size analysis, x-ray diffraction (XRD) and scanning electron microscopy (SEM). XBent acting as a type of environmentally friendly adsorbent was applied to remove lead ions from ...
