Investigation of The Effect Of Initial Metal Ion Concentration on Chromium (Iii) Adsorption onto Thebanana Leaf Petiole as the Biosorbent
(University of Embu, 2019)
There is a tremendous increasing demand for portable water due to the rising human population and urbanization and industrialization and climate change. There is no doubt that water in this county and largely the country ...
Effect of Varying Concentration of Strontium on Structural and Luminescent Properties of Sral2o3:Ce3+ Material
(University of Embu, 2019)
In modern world, luminescent materials with tunable emission properties have found application in most of the areas that usually deals with material sciences. White light emitting diodes have matched the efficiency of ...
Structural and Luminescent Properties Of Sral2o4:Ce3+ Nanomaterials Kamande
(University of Embu, 2019)
Blue and violent emitting cerium doped strontium aluminate nanophosphor was synthesised through solution combustion method. The colour of undoped SrAl2O4 powders was white while that of SrAl2O4: Ce3+ powders were pale ...
Synthesis And Investigation Of Properties Of Cerium Doped Calcium Oxide (Cao: Ce3+ )
(University of Embu, 2019)
Over the decade’s luminescent materials have found their use mostly in production of Light Emitting Diodes (LEDs), where different alkaline earth has been used in production of different colors. Phosphors have been used ...
Equilibrium Studies For Adsorption of Cadmium Ions Using Treated Maize Stalk Charcoal
(University of Embu, 2019)
Discharge of toxic heavy metals into the environment as industrial waste causes extensive soil and water pollution. The associated risk of pollution of heavy metals has increased over the recent years to a great extent. ...
Knowledge and Practise of Selected Integrated Soil Infertility Management Techniques in Embu West Sub-County
(University of Embu, 2017)
Soil fertility reduction due to soil nutrient depletion in Sub-Saharan Africa is a major challenge sustainable development of agriculture. Despite the ability of ISFM to improve soil fertility, less has been done towards ...
Investigating The Effect Of Adsorbent Dosage On Chromium (Iii) Ions Adsorption Onto Banana Petiole Biomass.
(University of Embu, 2019)
Water pollution has been the major cause of shortage of clean water in Kenya. This promptscitizens to use wastewater for domestic purposes. For example river Kapingazi in Embu wherewaste from the region is dumped is used ...
