Abstract

Background: Indole-3-acetic acid (IAA) is an important growth hormone for plants obtained by biosynthesis from tryptophan. Aim: In this paper was studied the competitive transport of two biologically active compounds, indole-3-acetic acid (IAA) and tryptophan (TRP) through a liquid membrane. Methods: The separation of the two compounds was obtained using a hybrid liquid membrane system having as a carrier trioctylphosphine oxide (TOPO). Results: The most important operational parameter of the system were studied, pH influence on the efficiency of the transport process in correlation with the speciation diagrams of the two compounds: TRP and IAA. The evaluation of the transport process was performed through calculating the composition of the phases at the end of the transport process and the organic substrate flow at the membranes exit. Conclusion: Due to the transport efficiency of over 90% in the case of IAA and the high selectivity at the transport between IAA and TRP, the procedure can be applied at the sample preparation containing these analytes.
