This study was conducted to evaluate the phytoremediation and phytomining potential of 10 plant species growing naturally at one of the largest lead–zinc mines in Northern Vietnam. Total concentrations of heavy metals and arsenic were determined in the plant and in associated soil and water in and outside of the mine area.

From raw material which is zinc flotation and powders from 50000-100000 tons ore / year, people take over the construction of two electrolytic zinc plants in Tuyen Quang and Bac Can. Each plant’s capacity is about 20,000 tones of zinc / year. Moreover the electrolytic zinc and lead making plants are expected to build in the 2008-2015 period.

Electrochemistry: Galvanic Cells and the Nernst Equation Step 3: Calculating cell potentials. In the preceding simulations you measured cell potentials of several cells made of various combinations of half-cells. It would be a monumental task to assemble a list of all possible cells and report a cell voltage for each. It is more useful to

Lesson 9: Standard Oxidation Potential (SOP) The ability of chemicals to gain and lose electrons can be quantified using a list of standard oxidation potentials.You will use such a list to determine which chemicals will spontaneously react with one another, which will react only if they are forced to do so, and what voltages can be generated by combinations of chemicals in voltaic cells.
- [Voiceover] Here we have a table of Standard Reduction Potentials, and this is a shortened version, but you can see on the left side, we have different half-reactions. All of these half-reactions are written as reduction half-reactions. Remember gain of electrons is reduction. If we look at our
