Therefore, it is the starting point of the research. By focusing on finding a เป็ย for each substance, environmentally friendly polymer used in the extraction instead of A.
Thus the starting point of this research. Our focus is on finding a solution into an environment-friendly. Used for the extraction of polymer instead of using A.
So it is the starting point of this research. With a focus on finding the solution, are environmentally friendly, used in the extraction of polymer instead of using A.
