Statistical Optimization and Desirability Function for Producing Nano Silica from Dune Sand by Sol–gel Method Towards Methylene Blue Dye Removal
This work aims to extract amorphous, high-purity silica nanoparticles (n-SiO2) from natural sand using the sol–gel method, a simple, economic, and environmentally friendly chemical process. The parametric optimization by Box–Behnken design was carried out to optimize the synthesis parameters (reacti...
