The global quadratic regression model exhibited extraordinary statistical robustness, achieving a total model sum of squares of 24,563.78 distributed across 20 degrees of freedom, yielding a mean square of 1228.19 and an exceptionally high F-value of 142.85 with p < 0.0001, unequivocally demonstrating that the regression model is highly significant at the 99.99% confidence level and that the selected variables collectively account for 98.92% of observed variance in Be 2+ adsorption capacity—leaving merely 1.08% attributable to residual experimental error.
