The Impact And Mechanism Of Chloride Ion Attack On Portland Cement Concrete And The Structural Steel Reinforcement Ife Journal Of Science
The minimum detectable concentration of manganese by the colorimetric procedures, working with a 100-ml sample, is 50 µg/liter. A concentration of .05 mg/liter or greater can be detected visually by the pink colour that is imparted to the water . Of the elements affecting disinfection, oxygen was most significant. These acid burns are typically superficial, only affecting the epithelial and basement membrane. Far more severe exposure will induce edema of both the upper airway and the lung parenchyma. Large acute…
