- Abstract
In the last few decades, different alternative materials are being tested for the adsorption treatment of waters polluted by heavy metals. Biosorption is particularly suitable for the treatment of polluted water in cases when the low heavy metal ion concentration is requested at the exit, and before pouring into the surrounding waterway, in order not to pollute the plant and animal life. Biosorbents are of significant importance in water purification processes due to their low cost, good performance and availability in large quantities. The paper presents the test results of lead and copper ion sorption from synthetic solutions in the barley straw as adsorbent. Biosorption of lead and copper in the barley straw is carried out by ion exchange mechanism, whereby the lead and copper ions are replaced by calcium and hydrogen content in the molecular structure of the straw. The obtained results show a significant influence of pH values on the removal efficiency of the metals in the process of biosorption. The results show that barley straw can be used as an inexpensive, natural adsorbent for lead and copper ion sorption from aqueous solutions.
