Removal of Cr(VI) from wastewater using iron oxide nanoparts from leonardite and waste ash extract

In recent years, alternative treatment methods have been developed to characterize the diversified fibers in wastewater. Wastewaters containing heavy metals cause the necessary threat to the receiving environment and abuse them in living things. Chromium (Cr) is one of the most dangerous devices derived from industrial products containing heavy metals such as mining and metallurgy. Recently, attention has been paid to the economic improvement of wastewater that is harmful to the environment and contains heavy metals such as Cr(VI) and its treatment with environmentally friendly preservatives. It is possible to obtain REMOVAL OF CR(VI) FROM WASTEWATER USING IRON OXIDE NANOPARTS FROM LEONARDITE AND WASTE ASH EXTRACT Cr(VI) removal from wastewater using a Fenton-like method and a classification. Leonardite is known to be derived from lignite oxidized during surfacing or represents humic-rich deposits. Leonardite occurs naturally as a result of the weathering of lignite deposits with a similar structure. It is derived from lignite with low consequences during surface exposure or represents sediment enrichment by humic acids leaching from the overlying lignite. The major difference between leonardite and lignite is the higher oxygen content of the former, entirely due to the greater number of carboxyl and phenolic groups. Carboxyl, humic acid and phenolic groups are found in leonardite. The major difference between leonardite and lignite is the higher oxygen content of the former, entirely due to the greater abundance of carboxyl and phenolic groups. This study aims to remove Cr(VI) deletion using Fe-NPs made from leonardite and waste ash extract by adjusting pH, layers, H2O2 amount, initial manager level, values and temperature parameters in solution in a Fenton-like process. Optimum values for 10 ppm Cr(VI) removal were obtained with pH 2.0, 2 g/L Fe-NPs and 0,2 mL/L H2O2 containers and 92,2% Cr(VI) removal. Zeta potential, SEM and EDX investigations to collect Fe-NPs are also on fire. The results show that the resulting Fe-NPs have a strong character for the Fenton-like process that removes Cr(VI) from aqueous solutions
