title: An important improvement in Ferron-timed spectrophotometry.
abstract: Ferron dosage ([Ferron]) is key to ferron-timed spectrophotometry (ferron assay). In order to clarify some important questions, the following studies were conducted: (1) The effect of [Ferron] on the sensitivity of total aluminum (AlT) determination was experimentally investigated and ²⁷Al nuclear magnetic resonance (²⁷Al NMR) spectroscopy was used to verify our developed Ferron assay; (2) the chemical equilibrium calculation was employed to analyze the effect of [Ferron] on the determination of AlT; and (3) the main reason for insufficient [Ferron] was further analyzed. This is the first study to standardize a ferron assay operating procedure.
