Analytical chemistry in technical approaches: immobilization of biosorbent waste containing heavy metals in cemented materials

چکیده
Abstract An ecologically safe and economically justified method of stabilization the used biosorbents was developed. Sorbent contaminated with heavy metals has been successfully solidified/stabilized using a hydraulic binder. The test results indicated that up to 1% biosorbent residue could be added without compromising compressive strength mortar. modified mortars did not change significantly even after 20 freeze/thaw cycles. analytical methods such as Flame Atomization-Atomic Absorption Spectrometer, Graphite Furnace-Atomic Cold Vapor-Atomic Spectrometry were utilized examine leaching behavior selected during harsh condition exposure. leachability found below limit allowed by US EPA immersion agitation for 10 days in artificial water solutions (seawater, groundwater, rainwater). X-Ray Diffraction Brunauer–Emmett–Teller data showed no significant changes crystalline structure surface area treatment. Research mixing adsorbent mortar effective immobilizing implementation so-called ‘zero waste’ management method. Graphical abstract

متن کاملGenetic risk assessment of acid waste water containing heavy metals.
The mutagenic/cancerogenic potential of acid-mine water from the Slovak mining area Rudnany containing a high load of toxic metals was evaluated after its application to three model test organisms (bacteria Salmonella typhimurium, yeast Saccharomyces cerevisiae and plant Vicia sativa L.). The results obtained from the modified preincubation Ames assay proved that 1000-fold diluted waste water e...
متن کاملFrequency of electronics-waste generated heavy metals in urban waterways
Heavy metals are one of the dreadful environmental pollutants. Its toxicity is a menace to the ecosystem and has attracted global concern over the decades. The attendant uncontrolled disposal and recycling of electronic-waste (e-waste) has greatly influence the elevated concentration of heavy metals observed in Nigeria waterways. This study was carried out to investigate the frequency of the de...
