Physical deterioration of the solid matrix as a result of erosion or cracking, as well as. While a liquid is easier to compress than a solid, it is still quite difficult imagine trying to compress water in a confined container! Water is an example of a liquid, and so are milk, juice and lemonade. Water is all around us. Water can be a liquid like rain or in rivers, lakes and oceans. Snow and ice are solid water. Several methods of extraction and analytical determination for total petroleum hydrocarbons (TPHCs) in aqueous and solid samples are reviewed.
Liquid / Liquid Extraction (L/L or SLE) Liquid / Liquid extraction is a technique for extraction of samples based partitioning of compounds between a polar and non-polar solvent.
