Keywords: chloride in concrete, near-infrared spectrometry, rapid determination. 1. INTRODUCTION. 1.1 Background. Penetration of chloride ions into concrete is a well-known problem, because it eventually results in. corrosion of rebars, leading to cracks, spalling, delamination and other roadway defects [1]. The problem is. particularly acute in bridge decks, which are subject to frequent salt applications during the winter months.
To prove that the solution is gold chloride simply requires proof that the cation is gold and the anion is chloride. The gold cation can be measured using atomic absorption/emission techniques or by using an ion selective electrode (ISE). Either test requires equipment available in many testing laboratories.old hydroxide is a gold salt which is not water soluble, making the claim scientifically impossible! For more details on ionic solubility see Solubility Rules. The chloride test described below demonstrates that products claimed to be ionic gold and gold hydroxide are really gold chloride.
