Simultaneous detection and determination of mercury (II) and lead (II) ions through the achievement of novel functional nucleic acid-based biosensors. Among the halides, the iodide is less soluble than the bromide, which, in turn, is less soluble than the chloride. In the tetragonal form the four leadoxygen bonds have the same length, but in the orthorhombic two are shorter and two longer. Lead compounds are poisons. Heat carefully at first, then strongly with a hot Bunsen flame, until the mixture becomes molten and runny. PENOX Group is able to supply all grades of lead oxide with specific characteristics to achieve modern battery requirements including Start-Stop but also for high temperature applications .
