That element or substance which are found in very less quantity in nature chromatography method is used in purification and separation of components from their mixture it is an adsorption technique and it is based on the distribution of mixture between two-phase.
In the form of the station, 3 phase choice of add job and is based on the principle that different compound of a mixture are differently at the job it depends upon the physical state three nature mobility and provides information about them so it is known as chromatography on the basis of adsorption principle and the nature of mobile and stationary phase.
Types Of Chromatography –
A very useful method for purification of the element which is available in nature in minute quantity and the impurities are not very different in chemical properties from the element to be provided in the method. A cylindrical column of glass is taken at the button of the column there is a take test of absorption with suitable liquid is mad are been then the column is filled with it as an option should be completely insoluble in liquid and it should not react with the component of the sample mixture.
Example of adsorbent aluminium jazz silica gel calcium carbonate starch cellulose mixture those compound are two separated is dissolved in a suitable solute-solvent and passing slowly into the column different components on the basis of their average option power are absorbed in different levels of the columns component of mixture haveli adoption power is adsorbent in the upper part of the column and having less adoption power is observed in the slightly low part of the column
Due to this different component are separated in Kollam containing different bond these bonds are identified by different columns or ultraviolet light these bands are taken out of the column and separated by cutting such component is dissolved in a suitable solvent is known and add Lucent and then extraction is done
Crystallization r is converted into power form the after then the concentration of our is used to increase the concentration of RZ and is reduced and converted into zinc oxide is also reduce with Coke zinc oxide is mixed with coke and sand and the mixture is converted into small bricks are then fitted in the Florence after this zinc oxide is reduced by carbon-zinc metal is called by distillation and sudden cooling of method that zinc metal obtained by the above method is 97.8 percentage pure
Roasted are is mixed with silica and cock is blast furnace into the following reaction occurs the graphical representation of Gibbs free energy change versus absorption temperature for metal energy pass is known as selling name design.
Uses Of aluminum
Aluminum is used for making electrical transmission cables (Good Conductors of Electricity). Aluminum files are used for wrapping cigarettes, foodstuffs, soaps, etc.
Uses Of Copper
Copper is used for making the electronic wires used in the electronic industry and for water and steam pipes. This is because of the very high electrical conductivity of the copper. Copper is also used in the electroplating and the electrotyping industry.
Uses Of Zinc
Zinc is used for galvanizing the irons. The zinc is also used in the extraction of the gold and the silver by this cyanide process.
Uses Of Iron
Cast iron which is the most important form of the ions is used for casting the stocks, the railway sleepers, the toys, etc. The ions are also used in the process of manufacturing of iron and steel.
Extraction Of Zinc From Zinc Oxide
Crystalline ore is converted into powder form and after the concentration of ore is used to increase the concentration of ore. Zinc Oxide is reduced and converted into zinc. Zinc Oxide is also reduced with coke. Zinc oxide is mixed with coke and sends the mixture is converted into small bricks. These bricks are then heated in the furnace after this zinc oxide reduced by the carbon and ‘zn’ metal is collected by the distillation and sudden cooling of this method.
