Peanut husks, one of the biggest food industry waste products, could be used to extract environmentally damaging copper ions from waste water, according to researchers in Turkey. Writing in the Inderscience publication the International Journal of Environment and Pollution, the team describes how this readily available waste material can be used to extract toxic copper ions from waste water. The discovery offers a useful alternative to simple disposal of this ubiquitous food industry waste product.
Copper is an essential trace element found in many living organisms, but at high levels it is potentially harmful and when discharged at high concentration into natural water resources could pose a serious environmental threat to marine ecosystems. Various industries produce waste water containing dissolved copper(II) ions, including those that carry out metal cleaning and plating, paper pulp, paper board mills, and wood pulp production sites and the fertilizer industry.
Conventionally, various relatively sophisticated processes including copper salt precipitation, ion exchange, electrolysis, and adsorption on expensive activated carbon filters are used to remove copper ions from waste water.
Now, Duygu Özsoy and colleagues in the Department of Environmental Engineering, at Mersin University, Turkey, have begun investigating the potential of several materials to absorb the dissolved form of copper from waste water. They have looked at how well untreated peanut husks and another potential cleanup material, pine sawdust, compare in absorbing copper ions from waste water.
The team measured the levels of copper ions that could be extracted from waste water at different temperatures, acidity, flow rate, and initial concentration of dissolved copper.
They found that, as expected the longer the waste water is exposed to the materials the more efficient the process. However, there is a stark difference between peanut husk extraction and pine sawdust. The peanut husks could

    The objective of this experiment was to identify the unknown pure copper salt compound of #9. To do this, the mass of copper in the unknown was calculated and then divided by the mass of the whole compound to get the percent copper. The molecular weight was also calculated by dividing mass of copper compound used by moles of compound in unknown sample. The percent copper averaged out to 31.6% while the molecular weight of the sample averaged out to 201.1mw. In conclusion, the unknown compound of pure copper salt was close to Cu(C2H3O2)2 •H2O which has a percent copper of 31.8% and a molecular weight of 199.654mw.…

    In this lab we attempted to use electrochemistry to extract metals from ionic compounds in solution. In order to extract a metal from a solution, we had to use electrochemistry. To get the copper out of the solution, we used a battery to get an electric current to go through the solution and cause an electron transfer. Because the copper is a cation and the nickel plates had a negative charge when the electricity was flowing, the copper was attracted to the nickel plates and therefore the copper became neutral. We can conclude that the copper gained 2 electrons because the copper was separated from the copper sulfate solution and then coated one of the nickel…

    There are two main methods used to extract copper from its ores. Generally, copper is extracted using the Pyrometallurgical method (also known as smelting), which allows us to separate copper from its sulfide and oxide ores; the other method, called the Hydrometallurgical method (also known as solvent extraction or electrowinning - SX/EW), allows us to also separate copper from its oxide ores. Although this method is more cost effective, it only accounts for a very limited amount of the world’s copper production as its environmental impact is much stronger than that of pyrometallurgy - the by-products of hydrometallurgy contain much higher concentrations of sulfur and metal particulates.…

    In order to create successful chemical reactions, we followed the procedures properly. We started with a small amount of cooper powder in a beaker, and added nitric acid to it while the beaker was under a fume hood. We removed the beaker as soon as it was safe to and next we added 25mL of water to the current blue solution. We then added sodium hydroxide to the beaker and then proceeded to place the beaker on to a hotplate and stir the solution with a stirring rod. We then removed the beaker with tongs off of the hotplate and filtered the solution with a filter paper and funnel. The next day, after the solid had dried onto the filter paper, we scraped the solid off and into the beaker with a spatula. We then added sulfuric acid and zinc, respectively, into the beaker. We stirred the solution and our final step was getting rid of the liquid waste and observing the copper powder at the bottom of our beakers.…

    Kills bacteria Copper has the ability to naturally sterilize and can fight off the development of bacteria, especially S. aureus and E. Cali. Both of these bacteria can lead to serious illness and are known to be quite widespread in the environment. The use of cooper can help to minimize the outbreak of waterborne diseases such as jaundice, dysentery, and diarrhea.

    Copper is one of the few metals that have been mined for more than 100 decades globally. According to M.G.C Wilson (1989) copper has been mined since the early 3000 BC in Cyprus. In the ancient times copper was used for making tools, weapons, ornaments and many household utensils. Copper is the third most widely used metal after aluminium (Al) and iron (Fe) because of its high durability (Doebrich et.al,2009). In the Southern African region copper has been extracted by the early inhabitants long before 1598, where Vasco Da Gama circled the Cape of Good Hope and realised the quantity of copper that was extracted by the people (Wilson M.G.C, 1989). Copper is an element that occurs in minor amounts in the Earth's crust. Copper mines are found…
