Simultaneous determination of borate, chloride and molybdate in pyrohydrolysis distillates of plant and soil samples by ion chromatography

摘要

Highlights?An IC method is proposed for simultaneous separation and determination of B, Cl and Mo as borate, chloride and molybdate.?Concentration gradient elution ofd-mannitol (essential for separation and detection of B)and NaOH eluent was employed.?d-mannitol does not affect separation of MoO42? but decreases its detection sensitivity due to formation of Mo-mannitol complex.?Developed method was successfully applied to the pyrohydrolysis distillates of plant and soil samples.AbstractDetermination of concentrations of micronutrients in plant samples is important in order to assess the growth and quality of plants. An ion chromatography (IC) method was developed for the simultaneous determination of B, Cl and Mo (micronutrients present in their anionic form in aqueous samples) using
