A transcription and concentration method of Al tridecamer (Al 13 ) to Chelex 100 chelating ion exchange resin was developed to enhance the in situ detection sensitivity of the Al 13 in an aqueous solution by 27 Al magic angle spinning nuclear magnetic resonance. Based on this method, a new lower limit of Al concentration (at least 10 −4 mol/L) required to form Al 13 was discovered, which is the lowest detectable level known to date. It was found that once Al 13 is transferred onto Chelex 100, which serves as a model compound of a soil surface covered with organic substances and microbes, its stability against pH is considerably enhanced (stable at pH 4–12).
