Sorption of Copper Ions by Biogenic Iron Sulphides

Biogenic iron sulphides are excellent adsorbents for various heavy metals ions. Consequently, they have practical application for the elimination of heavy metals from waste waters. One of the principles for the iron sulphides preparation is the application of sulphatereducing bacteria. This biological-chemical method is based on the ability of these bacteria to reduce sulphates to hydrogen sulphide, which binds with the ferrous cations to form insoluble precipitates – iron sulphides. Under certain bacterial growth conditions biogenic iron sulphides can be magnetic. The aim of this work is to study the possibility of using SRB for the preparation of iron sulphides, which were used subsequently in the framework of sorption tests to eliminate copper ions from model solutions.

The article presents the results of experimental research for final treatment of gold mining enterprise waste waters using water lentil (Lemna minor) of (Lemna L. ) genus, (Lemnactat S.F. Gray) family, and common red grass (Phrágmites austrális (Cav.) Trin. Ex Steud.). It was shown that a level of heavy metals extraction, cyanides and rhodanides from the industrial waters of gold processing plant is greatly higher in comparison with chemical method used at the plant. The proposals are given to the gold mining enterprise to establish a pilot plant for final biological treatment, its novelty is confirmed by the Patent of Russian Federation of 20.01.2014.

Coated Sand

Adsorption is most commonly applied process for the removal of pollutants such as dyes and heavy metals ions from wastewater. The present work talks about preparing graphenic material attached sand grains called graphene sand composite (GSC) by using ordinary sugar as a carbon source. Physical morphology and chemical composition of GSC was examined by using (FTIR, SEM, EDAX and XRD). Efficiency of GSC in the adsorption of organic dyes from water was investigated using reactive green dye with different parameters such as (ph, temperature, contact time and dose). Adsorption isotherm was also studied and the results showed that the maximum adsorption capacity of dye is 28.98 mg/g. This fast, low-cost process can be used to manufacture commercial filters to treat contaminated water using appropriate engineering designs.
