Effect of anthropogenic activities on the water quality of Amala and Nyangores tributaries of River Mara in Kenya
Nyairo, Wilfrida N; Owuor, Philip O; Kengara, Fredrick O (2015-10-30)Abstract Mau Forest in the upper reaches of the Mara River basin has recently undergone increased forest destruction followed by human settlement and agricultural activities. These anthropogenic activities may be ... -
Efficient adsorption of lead (II) and copper (II) from aqueous phase using oxidized multiwalled carbon nanotubes/polypyrrole composite
Nyairo, Wilfrida N; Eker, Yasin R; Kowenje, Chrispin; Akin, Ilker; Bingol, Haluk; Tor, Ali; Ongeri, David M (Taylor & Francis, 2018-01-12)Polypyrrole coated oxidized multiwalled carbon nanotubes (oMWCNT/Ppy) were applied to determine the adsorption characteristics of Pb(II) and Cu(II) from their aqueous solutions. Structural and morphological characterization ... -
Efficient removal of lead (II) ions from aqueous solutions using methyl-β-cyclodextrin modified graphene oxide
Nyairo, Wilfrida N; Eker, Yasin R; Kowenje, Chrispin; Zor, Erhan; Bingol, Haluk; Tor, Ali; Ongeri, David M (Springer International Publishing, 2017-11-01)Graphene oxide (GO) and graphene oxide modified with methyl-β-cyclodextrin denoted as GO-mβCD were prepared and applied as adsorbents to determine the adsorption characteristics of Pb(II) from aqueous solutions.
