Salinity and pH Effects on Gelation Time of a Hydrogel Using CCD Method

What is it about?

The main purpose of this research was to establish a functional relationship of gelation time in terms of pH and salinity factors via the experimental design matrix proposed by the CCD approach. The significant factors that affect the gelation time are presented with the development of a quadratic mathematical model. The optimized model with respect to the selected factors well predicted the maximum gelation time for a particular salinity and pH condition.

Why is it important?

In order to present the general result, for the range of both of the experimental variables of the studied factors, response surface methodology (RSM) was used to obtain the interactions of salinity and pH. Central composite design (CCD), as the most popular form of RSM, is used extensively in building the second order response surface models.
