1. What is Mass of Gas Adsorbed?

Definition: The Mass of Gas Adsorbed is the amount of gas that reacts with or is taken up by an adsorbent material.

Purpose: This calculation is crucial in chemical engineering, environmental science, and industrial processes involving gas purification or separation.

2. How Does the Calculator Work?

The calculator uses the Freundlich adsorption isotherm formula:

Where:

• \( x_{gas} \) — Mass of gas adsorbed (kg)
• \( m \) — Mass of adsorbent (kg)
• \( k \) — Adsorption constant (dimensionless)
• \( P_{gas} \) — Pressure of gas (Pascal)
• \( n \) — Freundlich adsorption constant (dimensionless)

Explanation: The formula describes the relationship between the quantity of gas adsorbed by an adsorbent and the gas pressure at constant temperature.

3. Importance of Gas Adsorption Calculation

Details: Accurate calculation helps in designing adsorption systems, predicting purification efficiency, and optimizing material usage in industrial processes.

4. Using the Calculator

Tips: Enter the mass of adsorbent, adsorption constant, gas pressure, and Freundlich constant. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the Freundlich adsorption isotherm?
A: It's an empirical relationship between the quantity of gas adsorbed by an adsorbent and the gas pressure at constant temperature.

Q2: How do I determine the adsorption constant (k)?
A: The constant is typically determined experimentally for specific adsorbent-gas pairs at given temperatures.

Q3: What affects the Freundlich constant (n)?
A: It depends on the nature of the adsorbent, the gas being adsorbed, and the temperature of the system.

Q4: Can this be used for liquid adsorption?
A: The Freundlich isotherm can be adapted for liquid-phase adsorption with appropriate constants.

Q5: What are typical values for the Freundlich constant?
A: The value typically ranges between 1 and 10, with higher values indicating more favorable adsorption.
