“…In addition, the aggregation or overlapping of biosorbent surface area and competition for available sorption sites for metal ions adversely impacted the biosorption efficiency (EI-Sayed 2013). This result is in good agreement with those obtained in other studies (Masoudzadeh et al 2011;Khadivinia et al 2014). Based on the aforementioned result, the suitable biosorbent dosage was 1.5 g L -1…”

“…However, the results obtained in the present study showed no significant difference in biosorption rate or capacity between the lowest and highest temperatures. Energy-independent mechanisms suggest that adsorption efficiency can hardly be affected by temperature, since this biosorption is physicochemical (electrostatic forces) process in nature (Khadivinia et al 2014). In our case, the biosorption is well performed at 30°C, which is taken as a cost-effective temperature for practice.…”

In this study, strain BAPb.1 was isolated from lead mining area and used as an adsorbent to remove lead(II) ions from aqueous solution. The physicochemical characteristics, heavy metal resistance and antibiotic sensitivity of strain BAPb.1 were investigated. Biosorption capacity was evaluated by batch biosorption experiments, and isothermal characteristics were discussed. Atomic force microscopy (AFM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX) and Fourier transform infrared spectrometry (FTIR) were conducted to explore the mechanism for lead(II) adsorption. Based on morphological and physiological characteristics as well as the phylogenetic analysis of 16S rDNA sequences, strain BAPb.1 was identified as a member of the genus Alcaligenes. It exhibited high resistances to multiple heavy metals such as lead(II), copper(II), zinc(II), nickel(II) and chromium(VI), and to antibiotics such as kanamycin, ampicillin, streptomycin, chloramphenicol, and tetracycline. The optimum conditions for maximum biosorption rate of 85.2% and maximum capacity of 56.8 mg g -1 were found at pH of 5, adsorbent dosage of 1.5 g L -1 (dry weight), initial lead(II) concentration of 100 mg L -1 , and contact time of 30 min at 30°C. Biosorption isotherms were well fitted with Langmuir isotherm model. Mechanism analysis reveals that the lead(II) ions may exchange with sodium and potassium ions, and the hydroxyl, carbonyl and phosphate groups on the cell surface can chelate the lead(II) ions, therefore, surface adsorption play significant role in the biosorption process.

“…external surface, and the second one, the inner layers, being energetically disadvantaged (Marco-Brown et al, 2014). At high concentrations, sorption does not increase due to the saturation of the sites by the available elements, unlike what occurs in low concentrations (Khadivinia et al, 2014).…”

“…Metal ions may also influence the sorption of herbicides in the soil. As pH increases, there is the precipitation of these ions, also reducing the interaction of herbicides with these metals (Khadivinia et al, 2014). When available, metal cations electrostatically attract negatively charged compounds (Lafferty and Loeppert, 2005;Shimizu et al, 2010), forming a cationic bridge (Nagar et al, 2014), which can raise the sorption of herbicides with a residual negative charge.…”

Tembotrione is registered in Brazil for maize and is used in large areas of the country in each harvest. In recent years, producers have reported carryover effects of this herbicide in succeeding crops to maize. This fact can be attributed to tembotrione recommendations without knowing their interactions with tropical soils colloids. In this study, using high-performance liquid chromatography, it was possible to evaluate the influence of chemical and physical attributes on the sorption and desorption of tembotrione, as well as its metabolite AE 1417268, on seven soils from different regions of Brazil. The coefficients referring to sorption and desorption, as well as the hysteresis index (Kf, 1/n and H) of tembotrione and its metabolite were influenced by pH, clay content and organic matter. In soil samples with low levels of clay and organic matter, values of sorption coefficients were reduced as pH increased. The desorption of tembotrione and its metabolite in all soils were low, mainly in the clayey ones and in soils with higher organic matter content. The sorption of tembotrione and its metabolites varies with the attributes of soil, presenting a direct relation with clay and organic matter contents and an inverse one with soil pH. The desorption of tembotrione and its metabolite decreased with the increase in clay and organic matter contents in the evaluated soils.

“…The resistance to multiple metal ion indicates that the resistance might have resulted from the presence of single or multiple genes present in their plasmids which may also confer antibiotic resistance to these bacteria (Yamina et al 2014). The industrial effluents are enriched media to grow and spread microbial population, which are resistant to different metals (Khadivinia et al 2014). The identification of bacteria resistance against different metals may provide a useful tool for the simultaneous monitoring of several toxic pollutants in the environment (Mohsenzadeh and Shahrokhi 2014).…”

In this study, we evaluated the ability of waste shell powder (WSP) and moringa seed powder (MSP) individually or in combination to eliminate dye, heavy metal and resistant bacteria from the industrial wastewater (IWW). The presence of dyes, heavy metals, approximately 7.0 log CFU/ml of aerobic bacteria and 3.0-4.0 log CFU/ml of other pathogens including Escherichia coli, Pseudomonas aeruginosa, Citrobacter freundii, Serratia liquefaciens and Bacillus cereus was evident in IWW of both tannery and textile industries. In addition, depending on the type of bacterial species each bacterium was resistant to as high as 50 ppm of multi-metal (Cr 6+ , Cd 2+ and Pb 2+ or its combination) and even multi-drug resistant (amoxicillin, ampicillin, cefixime, ceftazidime, and tazobactam). Combined use of MSP (0.8 gm/100 ml IWW) and WSP (0.2 gm/100 ml IWW) treatment was able to discolor the IWW within 4 h and took 24 h to eliminate heavy metals and pathogenic bacteria to non-detectable level from the IWW, simultaneously. On the other hand, individual use of MSP or WSP was not found effective enough to remove or eliminate dye, heavy metal and bacteria simultaneously from the IWW. Similar experimental results were observed in the challenge test with laboratory-prepared effluent water containing 35.0 ppm Remazol Brilliant Blue R dye and maximum 50 ppm Cr 6+ . Thus, the combination of these two bio-sorbents could be applicable in IWW treatment before being discharged into the environment.
