“…The percentage extraction when using UROSE increased from 87.7% to 94.2%, while for AmROSE, it increased from 90.3% to 98.2% and for APmROSE, it increased from 93.2%, to 99.8%. The same observation of increase in agitation time giving a corresponding increase in percentage extraction has been reported by previous authors [1,8,24,28,29], and can be attributed to increase in collision frequency. Overall, APmROSE ligand showed the highest percentage extraction of Cu , followed by AmROSE and UROSE respectively.…”

This study investigated the use of unmodified red onion skin extract (UROSE), aniline modified red onion skin extract (AmROSE) and 2-aminophenol modified red onion skin extract (APmROSE) for the extraction of copper (II) ions from aqueous media. The effect of pH, agitation time, ligand concentration and metal ion concentration on the percentage extraction were explored. The stoichiometric coefficients of the metal ions and the ligands (UROSE, AmROSE and APmROSE) in each extraction experiment were determined using slope analysis. The results revealed that the percentage extraction of copper (II) ions increased with increasing ligand concentration and agitation time and decreased with increasing initial concentration of copper (II) ions. The optimum pH for the extraction of copper (II) was found to be 6.77, 6.10 and 2.57 for UROSE, AmROSE and APmROSE respectively, while slope analysis showed that UROSE, AmROSE, and APmROSE ligands reacted with the metal ion in 1:1 molar ratio.

Consumption of food and water contaminated with heavy metals poses a huge threat to the life. Both of Lead (Pb) and Cadmium (Cd) are heavy metals and important environmental pollutants. Away from traditional treatments, the current study aims to adopt probiotic bacteria Pediococcus pentosaceu to treat heavy metal pollution. Present results indicated a good probiotic property of P. pentosaceus, where they were able to survive pH range from 3-9, during incubation periods 3 and 24 hours, and bile salt range 0.15-0.5% for the same period. The number of bacteria in gastric (pH 3) and intestinal juices (pH 8) after 24 hours of incubation was 390 and 205, respectively. Bacteria showed an inhibitory effect against pathogenic bacteria Salmonella sp. The antibiotic susceptibility test revealed them resistant to clindamycin, intermediate resistant against benzylpenicillin, ampicillin, and their sensitivity to the rest tested antibiotics. Isolated bacteria identified based on their morphology, biochemical characteristic in addition to the use of automated instrument for bacterial identification (Vitek II), and depending on the results bacteria were identified as P. pentosaceus. In bioremediation study, the lowest inhibitory concentration of lead and cadmium and (MIC) was done, followed by assay the removal capacity by P. pentosaceus, using atomic absorption spectrometry (AAS) analysis. Bacteria show high MIC (1800 and 150 ppm) for Pb and Cd respectively. With removal efficiency for Pb 62.10-68.39% in the concentrations 25 and 50 ppm, respectively, and for Cd 52.71-11.25% in the same concentrations. Depending on the present finding probiotic bacteria (P. pentosaceus) can apply in the bioremediation of heavy metals in the fish ponds when contamination occurs, in addition to their tradition used as safety additive to prevent fish disease and an enhancement agent .Finally the isolation of these bacteria from fish ponds can be considered as a good indicator for a healthy state of fish ponds in the studied area.

“…Only a portion of this waste is used by farmers as animal feedstock. In a previous study, fava bean powder was used for the removal of heavy metal ions of Pb(II), Cd(II) and Zn(II) 37 to achieve removal efficiencies of 100%, 92.86% and 36.86%, respectively. Broad bean peels, on the other hand, were utilized to remove MB dye with a maximum adsorption capacity of 192.7 mg g −1 at 30 °C 38 .…”

Fava bean peels, Vicia faba (FBP) are investigated as biosorbents for the removal of Methylene Blue (MB) dye from aqueous solutions through a novel and efficient sorption process utilizing ultrasonicassisted (US) shaking. Ultrasonication remarkably enhanced sorption rate relative to conventional (CV) shaking, while maintaining the same sorption capacity. Ultrasonic sorption rate amounted to four times higher than its conventional counterpart at 3.6 mg/L initial dye concentration, 5 g/L adsorbent dose, and pH 5.8. Under the same adsorbent dose and pH conditions, percent removal ranged between 70-80% at the low dye concentration range (3.6-25 mg/L) and reached about 90% at 50 mg/L of the initial dye concentration. According to the Langmuir model, maximum sorption capacity was estimated to be 140 mg/g. A multiple linear regression statistical model revealed that adsorption was significantly affected by initial concentration, adsorbent dose and time. FBP could be successfully utilized as a low-cost biosorbent for the removal of MB from wastewater via US biosorption as an alternative to CV sorption. US biosorption yields the same sorption capacities as CV biosorption, but with significant reduction in operational times. Considerable amounts of synthetic dyes are used in many process industries. Textile, pharmaceutical, leather, food processing, cosmetics, and paint industries discharge into the environment about 10-15% of over 0.8 million ton of several types of dyes produced annually worldwide. It is projected that the dye business will grow annually by about 2-3% due to the increased global production and consumption of dyes. In developing countries like India and China, the production rate of dyes is increasing steadily every year. Without proper treatment, these dyes harm the environment, marine life and pose serious health threats to humans particularly upon degradation as they become toxic, recalcitrant, mutagenic, and carcinogenic 1-3. Methylene blue (MB) (3,7-bis(Dimethylamino)-phenothiazin-5-iumchloride) is a thiazine cationic dye commonly used for biological staining as well as coloring paper, hair, cottons and wools 4. In addition, MB injection is used in the treatment of methemoglobinemia and urinary tract infections. However, accumulation of MB in wastewater has adverse health effects such as difficulties in breathing, vomiting, eye burns, diarrhea and nausea 5. Several physicochemical and biological processes have been successfully carried out in order to treat dye effluents 6 , examples of which are membrane filtration 7 , photocatalytic degradation 8 , irradiation 9 , biological treatment 10 , conventional adsorption 11 and ultrasonic-assisted adsorption 12. Adsorption is a commonly employed strategy due to its relative facile operation, availability of its adsorbents, selectivity and potential for scale-up. Among employed adsorbents, activated carbon is commonly used due to its efficiency and high surface area 13. However, it has substantial limitations due to its high cost of regeneration and its imp...
