Adsorption Experiment
This paper will be discussion the adsorption experiment conducted in Dr.O lab class. This paper will cover what Chitin/Chitson are but before explaining what these are it is best to get an understanding of what adsorption, absorption and sorption are. Adsorption is the accumulation of gases, liquids, or solutes on the surface of a solid or liquid. This binding is very weak. Almost anything such as fluids that dissolves can break the binding of the molecules. In addition adsorption has many uses such as the removal of toxic or recalcitrant organic pollutants from wastewater. The most common adsorbents on the market today are activated carbon, silica gel, and alumina, because they have large surface areas per unit weight. Activated carbon is produced by roasting organic material to decompose it to granules of carbon - coconut shell, wood, and bone are common sources. Also activated carbon is the most commonly used adsorbent in wastewater treatment. As Silica gel is a matrix of hydrated silicon dioxide. Alumina is mined or precipitated aluminum oxide and hydroxide. Adsorptions Isotherm equation is q=f(C) where q is the mass of the adsorbed species and C is the equilibrium concentration of absorbable species in the solution.

Figure 1.This is an example of an Adsorption Isotherm.
However absorption is different.
Absorption is a process in which either liquid or light is absorbed. Between the two absorption is the least commonly used in environmental engineering. For example when a human being applies lotion on their skin and after a couple of minutes it disappears. What happened there was that their skin absorbed the lotion. In addition absorption comes in many different context such as: Chemistry, skin , pharmacokinetics, CO2 scrubber , electromagnetic radiation and etc. However, when speaking about adsorption and absorption the clear difference should always be idenfited. The difference between adsorption and absorption is that...
