Ortho-experiment study on formation of potassium sulfate from the system of K+,Ca2+,NH4+parallel to Cl-,SO4(2-) in H2O
An ortho-experiment design and the analysis method of mathematical statistics are adopted to study the conversion of gypsum and potassium chloride to potassium sulfate in the system of K+, Ca2+, NH4+ \\ Cl-, SO42- in H2O. Optimal reaction parameters and engineering mean are acquired to attain a conversion yield of potassium chloride of 94.52%.
