• Adsorption kinetics
2.1 Adsorption kinetics
01 CONCEPTS: • Adsorption kinetics: Adsorption kinetics is a branch subject that studies adsorption, desorption speed and various influencing factors, which is a time-dependent process. It is necessary to know the rate of adsorption for design and evaluation of adsorbent. (化学化工大辞典； Saeid Azizian，2004）

2.1 Adsorption kinetics
03 Fitting adsorption kinetics equation:
What else do you need? How to fit the equation?
1. Design experiments according to literature what you read. 2. At the beginning of reacting, the sample time should be more intensive than the later. 3. Select one indicator as a response
Experimental data
Origin
1. Input experimental data and draw scatter plot. 2. Analysis→ fitting→ nonlinear curve fit →settings (category)→ New category(name)→ New function （input the objective function)→ code builder→ compile(done)→ return to dialog→ save→ ok →settings→ name→ parameters→value→fit 3. Output results including parameters and R 2
