Potassium sulphate production from an aqueous sodium sulphate waste from lead acid battery recycling
… reactors indicated a significant decrement of potassium (K) and chlorine (Cl) molecules when the level of impurities was varied from 1% to 10%. Between the impurities levels of 0 to 3%, yields of both k2SO4 and NaCl greater 90% were achieved. Thereafter, the yields dropped below 90%. This …

A study of the drying of single droplets in free-flight
… of significantly different solutions (sucrose, potassium sulphate) over a range of temperatures of 37oC to 97oC, initial concentrations of 5 to 40wt/wt% , and initial drop sizes of 2.8 to 4.6mm. Drop behaviour was recorded photographically and dried particles were examined by Scanning Electron …

Establishment of the relationship between the sediments mineral composition and groundwater quality of the primary aquifers in the Maputaland coastal plain
… drilling process. Maputaland aquifers are low in potassium, sulphate and magnesium ions. Sodium and chloride ions remain unevenly distributed throughout the entire selected Maputaland coastal plain aquifers. The Miocene Unit is characterized by two chemical signatures, calcium and bicarbonate ions …

Experimental and theoretical studies on the nucleation, growth and habit modification of some inorganic carbonates, phosphates and sulphates
… kinetics and growth of some inorganic sulphates and carbonates, in view of their growing importance as enviromentally friendly high surface area powders in detergent applications. Predictions of the crystal morphology based on lattice geometry laws have been obtained and compared to the …

Rauchgasseitige Korrosion von Nickelbasislegierungen für zukünftige 700C-Dampfkraftwerke
… hot corrosion behaviour. It is known that sodium sulphate may generate hot corrosion on those alloys at temperatures above its melting point of 884°C. On nickel base alloys an eutectic mixture of nickel sulphate and sodium sulphate with a melting point of 671°C can be generated, which leads to …
