Agents for chemical disinfection

Methods Of Disinfection
there are several methods which can be used for disinfection and these include
 * 1) Physical
 * 2) Chemical

Physical Method
these can include the use of hot air, ultrasoic and also dry air

Chemical Method
they can be further subdivided into 3 groups namely
 * Membrane Active Disinfection
 * Fixation Of Cell Membrane
 * Membrane Oxidizing

These oxidize the cell membrane of bacteria and this leads to the loss structure and ultimately cell death. Examples include iodine, sodium hypochlorate
 * Membrane Active Disinfection

These attach to the cell membrane of the bacteria and block the release of cell components. these include formaldehyde and glataldehyde
 * Fixation Of Cell Membrane

These oxidize the cell membrane of bacteria and this leads to the loss structure and ultimately cell death. Examples include iodine, sodium hypochlorate
 * Membrane Oxidizing

Several condition have to be taken into consideration when determining the effectiveness of the disinfectent and these are


 * 1) Spectrum of Activity
 * 2) pH of the acitvity
 * 3) Stability of Disinfection
 * 4) oncentration of Disinfection
