Adsorption Of Malachite Green From Aqueous Solutions Onto Rice Husks: Kinetic And Equilibrium Studies
(University of Nairobi, 2017)
A study was done to evaluate the removal of a cationic dye from simulated waste water onto rice husks (RH). Spectroscopic methods such as FTIR and SEM/EDX were used for adsorbent characterization. Experimental dependency ...

Compositional Analysis and Optical Properties of Co Doped Tio2 Thin Films Fabricated by Spray Pyrolysis Method for Dielectric and P Hotocatalytic Applications
(University of Nairobi, 2017)
Abstract Cobalt doped TiO2 thin films (CTF) deposited by spray pyrolysis has been studied. The compositional analysis has been done using RBS method, while optical spectroscopy has been done by measuring the transmittance ...
The food and beverage occurrence of furfuryl alcohol and myrcene—two emerging potential human carcinogens?
(University of Nairobi, 2017)
For decades, compounds present in foods and beverages have been implicated in the etiology of human cancers. The World Health Organization (WHO) International Agency for Research on Cancer (IARC) continues to classify such ...
A robust liquid chromatographic method for confirmation of drug stability of azithromycin in bulk samples, tablets and suspensions
(University of Nairobi, 2017)
A simple, isocratic and robust RP-HPLC method for the analysis of azithromycin was developed, validated and applied for the analysis of bulk samples, tablets and suspensions. The optimum chromatographic conditions for ...
