Green chemistry in synthesis and application of nano zero valent iron
2019-01-09 21:53:40

From more a decades ago, nano zero valent iron (NZVI) have been recognized as a promising option on environmental remediation, such as heavy metal adsorption from groundwater/wastewater. However, its direct use was inefficient due to the loss of reactivity: aggregation and surface oxide formation. In order to resolve the problem, use of supporting material along with its synthesis was suggested as a viable option. One problem regarding this technique is excessive use of additive chemical. In this study, use of exhausted coffee grounds, once regarded as wastes, is tried and its efficiency on NZVI supporting and application for environmental remediation are assessed.
