Central Composite Rotary Design
The Response Surface Methodology (RSM) is a collection of
mathematical and statistical techniques used for modeling and
analysis of problems, in which a response of interest is influenced
by several variables and its objective is to optimize this response
[18]. Central Composite Rotary Design (CCRD), a standard RSM
design was applied for seeking the optimum conditions for the
adsorption of urea from human urine on MACCS powder.
