Elemental Characterization of Rice Husk Ash from Local Rice Species in South Eastern Nigeria

Autor: I. J. Njoku, Placid Nwaokafor, Paul S. Ogbuefi, Ogechukwu J. Uzuegbunam

Publikováno v: Chemistry Africa. 3:1081-1085

Heavy metals such as Cr, Zn, As, Pb and Cu can be hazardous to health and the environment. The focus of this study is to investigate the trace metal constituents of rice husk ash (RHA) from Ikwo and Izzi rice clusters. RHA of Izzi CP, R8 and Ikwo CP

Assessment of the contamination of rice husk ash of Izzi CP, Ikwo CP and Izzi R8 rice species of South-Eastern Nigeria

Autor: Nnadozie Kennedy Okeke, I. J. Njoku, Placid Nwaokafor

Publikováno v: Environmental Challenges, Vol 5, Iss, Pp 100232-(2021)

In a previous study by the authors (Ogbuefi et al., 2020), the concentrations of heavy metals in Izzi CP, Ikwo CP and Izzi R8 were reported to be quite high. As an extension of the previous work, in the present work, pollution of rice husk ash (RHA)
