Abstract: Wheat flour is an important source of nutrient and as such is widely consumed in most part of the world, as bread and other pastries. Due to its high consumption, the presence of heavy metal at high concentration would be a significant health risk. Based on the soil in which the wheat was grown and the milling technology employed in making the flou... Show More

Abstract: The aim of this study was to apply experimental design in the optimization of the thia-Michael addition reaction between chalcone derivatives and mercaptans catalyzed by Fluorapatite catalyst (FAP). The central composite design was used to design an experimental program to provide data to model the effects of various factors on reaction yield (Y). ... Show More
