Ortho‐experiment study on formation of potassium sulfate from the system of K⁺, Ca²⁺, NH₄⁺ ‖ Cl⁻, SO₄²⁻ in H₂O

Abstract

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', NH: 1) C1-, SO:-in H2O. Optimal reaction parameters and engineering mean are acquired to attain a conversion yield of potassium chloride of 94.52%.
