Document Summary
Slope we can find ym maximum amount for weight of monolayer. Ym= number of drugs or gas adsorped in mono layer. Initially, the actual number of drugs of gas adsorbed at given partial pressure is expressed in this formula modify this equation of landgmuir isotherm. Find b and ym or we can use equation since we plot p/y as function of p, more convenient since from slope we can find ym, maximum amount for weight of monolayer. Many of the substances used by langmuir weren"t quite correct, in reality the surfaces aren"t uniform, there are higher peaks. Then if these aren"t met, then deviations from actual isotherm compared to theoretical one. Behavior dictated by landmuir equation, but we may have depletion of monolayer and farther adsorption and all other types of isotherm that aren"t well defined by landhair"s equation with the graphs 1-5.
