The aim of this work was to investigate the effect of aluminium (Al), a toxic metal for plant growth, as well as pH on the mobility of phosphate across a calcium-polygalacturonate (Ca-PG) network used as a soil–root interface model. The Ca-PG fibrils, having acidic properties, are able to complex ions selectively: thus a Ca-PG model could be useful to study the ion uptake by plants. Ca-PG networks were exposed to Al solutions at different concentrations (25, 100 and 200 μM) at pH 3.50, 4.00 and… CONTINUE READING
