摘要：

In this work canola meal (CM) was used for adsorption of copper. Adsorption of copper per unit of CM decreased with an increase in the concentation of the adsorbent. The pH did not affect the process very much. Increasing the initial copper concentration in the solution resulted in an increase of its uptake per unit of CM. A linear relationship between the final copper ion concentrations in solution and the uptake of the ions was observed for lower copper cocentrations while leveling off was noticed at higher concentrations; a Langmuir isotherm type model fits these experimental data. The uptake of copper ions was enhanced with decreasing canola meal particle sizes. The copper adsorption capacity of CM decreased with its phytic acid content reduction. Adsorption of zinc and cadmium by canola meal was higher than that of copper.
