The present work predicts a novel technique for treating workable results. It aims to more professional data treating
with less numbers of experiments. A Conceived Predictive Diagonal (CPD) technique is suggested for this target. For the
latter a non-linear regression procedure is applied using MATLAB software. Four published examples are employed and
treated. By remodeling rate of reaction -Arrhenius combination for studying a pair of factors simultaneously the
simulated results are very closed to that reported. It also successfully applied for lab scale uranium removal from nitrate
solution by Amberlite IR 120 at Nuclear Materials Authority, Egypt. This work demands skillful in matrices, nonlinear
regression modeling, MATLAB, and kinetics- thermodynamics relation
