Effects of nitrogenous fertilizer rates, plucking intervals and location of production on the micronutrient levels of clonal black tea.
Omwoyo, W Nyaigoti; Owuor, P Okinda; Ongeri, David M; Kamau, David M (International Society of Tea Science, 2014)Micronutrients are important to both animal and plant life. In plants, the levels can vary widely due to biotic and abiotic factors. Tea is widely grown and its beverages are claimed to be the most widely consumed ... -
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 ... -
