Benefits of ionic binding techniques 

• It is a relatively simple enzyme immobilization that requires minimum input. 
• Ionic bonding takes place under mild conditions such as room temperature and neutral pH, which helps preserve enzyme activity. 
• The ionic bonding can be reversed easily by altering the pH or by salting out of the enzymes. 
• It is easy to sustain an optimum pH though the entire reaction by controlling the acidity/alkalinity of the mixture, as the matrix that inactivates the enzyme is steadily charged.
