Abstract Cadmium-resistant bacteria that are used to remove cadmium (Cd) becoming increasingly of the most important and hygienic method. Resistant mechanisms involved in different ways, some them which can be removal techniques based on their molecular minimum inhibitory concentration (MIC). This review summarises recent improvements understanding by either intrinsically resistant or acquire r...

This study investigated the effects of four operational and environmental variables on the removal of trace metal contaminants from drinking water by electrocoagulation (EC). Removal efficiencies for five metals (arsenic, cadmium, chromium, lead and nickel) were compared under varying combinations of electrode material, post-treatment, water composition and pH. Iron electrodes out-performed alu...

in this work, an unstructured-type mathematical model was developed to simulatecadmium (cd2+) removal by desulfovibrio alaskensis 6sr, which is a recently described sulfatereducing bacterium, whose capacity for removing heavy metals are being studied. three processesare considered in the model: 1) the sulfate reduction process, 2) the consumption of lactate ascarbon source, and 3) the metal rem...

We developed a facile strategy for preparation of heteropoly metalate/graphene oxide nanocomposite as a new ion exchanger for cadmium ion removal from aqueous solution. The synthesized nanocomposite was characterized by X-ray powder diffraction (XRD), UV-Vis spectroscopy, FT-IR spectroscopy and Raman spectroscopy. Our findings indicated that the combination of heteropoly metalate nanoparticles ...

Heavy metals released by a number of industrial processes are major pollutants in marine, ground, industrial and even treated waste waters. Biosorption is a process that utilizes biological materials as adsorbents and several researchers have studied this method as an alternative technique to conventional methods for heavy metal removal from wastewaters. In this study, the efficiency of tea was...

The goal of this study was to identify Cd-resistant bacterial strains with endurance capacity and to evaluate their ability to remove cadmium ions from cadmium-polluted water. The Bacillus cereusS5 strain identified in this study had the closest genetic relationship with B. cereus sp. Cp1 and performed well in the removal of Cd2+ions from solution. The results showed that both the live and dead...

A sediment microbial fuel cell (SMFC) is a type of microbial fuel cell (MFC) that has recently attracted significantly attentions due to its unique property of removing organic and inorganic compounds from sediments. In this study the experiments were carried out in a dual-chamber SMFC with external resistances 30 kΩ-50 Ω. The SMFC was produced power about 630 mV with maximum power density 40 m...

Cadmium tolerance and removal in the marine microalga Dunaliella salina were studied in cultures exposed to different metal concentrations (5-120 mg Cd l(-1)) for 96h. This microalga can be included in the group of microalgal species most tolerant to cadmium due to the high value of EC50 that it possesses (48.9 mg Cd l(-1) at 96 h of culture). The greater percentage of cadmium removed was obtai...

There has been an increasing trend in the production and consumption of local and imported fruit juices in Iran. The presence of impurities and foreign matter in finished products for human consumption is of great concern because they present health hazards when they exceed beneficial limits. The manufacture of juices requires special attention in terms of purity and the sources of water and it...
