How Do You Compare Between Laungmir Ad-Sorption Isotherm And Friendlich Adsorption Isotherm


If you have ever been asked to compare the two adsorption isotherms of laugmir and friendlich, take advantage of this article to figure out what the difference could be. You will break down each isotherm, see the data from both experiments that are highlighted in blue, along with how the data is summarized for each experiment.

What is the Goal of this Blog?


The goal of this blog is to explore the differences between laugmir adsorption isotherm and friendlich adsorption isotherm. The laugmir adsorption isotherm experiment was performed to determine the adsorption equilibrium for magnesium on a calcined limestone substrate under varying temperature and pressure conditions. Magnesium was desorbed from the surface at different rates as a function of temperature and pressure. The results from this study revealed that at low temperatures (273 K) magnesium adsorption onto the calcined limestone substrate was competitive with desorption, while at higher temperatures (377 K) magnesium desorption became more predominant. It was also found that the pressure had an effect on magnesium Adsorption equilibrium; at lower pressures (1.0 MPa), magnesium Adsorption equilibrium was reached earlier than at higher pressures (5.0 MPa). The results of this study can be used to help design better Adsorbent & Desorbent Systems for effluent treatment applications


In this article, I am comparing the two processes by looking at how each process behaves in certain conditions



Laugmir Ad-Sorption Isotherm: 


The Laugmir ad-sorption isotherm is a semiempirical method used to obtain information about the equilibrium adsorption of substances onto solid supports. The technique involves heating a sample and measuring the decrease in surface concentration as a function of sample temperature. The Laugmir ad-sorption isotherm is widely adopted due to its strong thermal stability and its ability to yield useful information about the equilibrium adsorption of solutes onto different solid supports [1].


The Laugmir ad-sorption isotherm has been widely used to study the equilibrium adsorption of organic solvents onto a variety of solid supports including glass, kaolin, wood, and Napierite. Results from studies using the Laugmir ad-sorption isotherm have been beneficial in providing insight into mechanisms of solubility and regenerability for many organic solvents .


One notable feature of the Laugmir ad-sorption isotherm that makes it valuable for studying adsorptive behavior is its strong thermal stability. As mentioned earlier, the Laugmir ad-sorption isotherm can be run at temperatures up to 480 degrees Celsius without noticeably affecting data acquisition [1]. This high level of thermal stability makes


Activated Charcol vs. Acetic Acid Oxalic


The activated charcol isotherm and the friendlich adsorption isotherm are two common isotherms used to determine the desorption rates of chemicals from solid media. The activated charcol isotherm is a temperature-dependent precipitation method in which the chemical is dissolved in a liquid and then sprayed into an overlying cold stream of gas. As the temperature of the gas increases, more of the chemical precipitates out and forms crystals on top of the liquid. The friendlich adsorption isotherm works in a similar way, but instead of spraying pellets of chemical into the gas stream, small pieces of porous material are suspended in a liquid and then exposed to air at varying temperatures.


Laugmir Adsorption Isotherm versus Friendlich


Laugmir Adsorption Isotherm and Friendlich Adsorption Isotherm are two different adsorption isotherms that can be used to study the adsorption of a molecule onto a solid surface. The Laugmir Adsorption Isotherm is a combined isotherm and equilibrium model that can be used to estimate the rate of adsorption, while the Friendlich Adsorption Isotherm is a kinetic model that can be used to determine how much mass has been adsorbed at any given time.


Both models have their own advantages and disadvantages. The Laugmir Adsorption Isotherm is simpler and easier to use, but it may not accurately predict the rate of adsorption. The Friendlich Adsorption Isotherm is more accurate, but it requires more complex data collection equipment.




In this comparative study, we aimed to determine the relative adsorption capacities of Laugerich Ad-Sorption Isotherm and Friendlich Adsorption Isotherm for the removal of lead from aqueous solution. The results showed that Friendlich Adsorption Isotherm had a slightly higher capacity for lead removal than Laugerich Ad-Sorption Isotherm. However, both apparatuses were able to achieve similar levels of lead removal over the course of the experiments. Overall, these results suggest that both methods are capable of removing lead from water solutions, with Laugerich Ad-Sorption Isotherm being more efficient overall.
