Which of the following is NOT a method for measuring surface area of adsorbents? (2022)
Step 1: Understand what surface area measurement means. It refers to methods used to determine how much surface area is available on a material, like adsorbents.
Step 2: Identify common methods for measuring surface area, such as BET (Brunauer-Emmett-Teller) method, Langmuir method, and gas adsorption techniques.
Step 3: Recognize that thermogravimetric analysis (TGA) is a different technique. It measures how a material's weight changes as it is heated, which helps in understanding thermal stability and composition.
Step 4: Conclude that since TGA does not measure surface area, it is the correct answer to the question.
