Make Water Extraction Solvent
WATER EXTRACTION/SOLVENT EXTRACTION
Solvent extraction or water extraction is also called the method of separation is the best and popular. The main reason is the separation can be done either in the macro or micro level. The principle of this method is based on the distribution of solvents with specific comparisons between the two are not mutually solvent mixes, such carbon tetrachloride or chloroform. His limitations are dissolved substances can be transferred on a number of different the second phase of the solvent.
Extraction is the process of separation of a component of a mixture based on the distribution process of two kinds of solvents that are not mixed each other. Solvent extraction is commonly used to separate the desired cluster a number and probably the guys bullies in the overall analysis. Sometimes the cluster disruptor is extracted selectively.
Engineering work includes the addition of organic solvent in a solution of water containing the cluster in question. In the selection of organic solvents so that both types of solvent (in this case organic solvents and water) not mutually mixed with each other, Next the separation process is conducted in a separating funnel with its shuffling a few times.
1. price constant high distribution for the cluster is concerned and constant distribution of low to force the other pollutant.
2. low organic solvent Solubility in water
3. small Viscosity and does not form an emulsion with water
4. Non-flammable and non-toxic
5. it is easily pulled off back the cluster dissolved therein further analysis purposes ntk
The extraction can be performed continuously or gradually, gradually enough extraction is done by separating funnel. A mixture of two solvents are included with separator funnel, layer with a lighter type of weight is on the top layer.
With its, shuffling the extraction process takes place, given that the process of extraction is the process of equilibrium then separation of one layer of solvent can be made after the second type of solvent in the rest of the existing Coating. the bottom of the funnel with the expulsion from the opening tap funnels and guarded so as not to drown out the top layer. For the purpose of quantitative extraction done, preferably more than once.
