Comparative Study of Pb2+ Removals and Isotherms by Physically - and Chemically - Modified Agro - Wastes from Tanzania
(Gwangju Institution of Science and Technology, 2016)
Materials and Methods Raw corn and rice husk were washed several times using DIW to remove extraneous dirt and contaminants. The husks were then dried at 110 ºC overnight to remove moisture. Dried husks were then ground ...
Innovations and Sustainability: The Case of Improved Biomass Stoves' Adoption and Use in Tanzania
(Lund, Sweden – Spring, 2009)
The adoption and continued use of improved stoves in the developing countries is of social, economic
and environmental concern. In most developing countries, biomass-based energy accounts for more
than 90% of all household ...
Geochemical Distribution of Trace Elements in Groundwater from the North Mara Large-Scale Gold Mining Area of Tanzania
(Ground Water Monitoring and Remediation, 2016-05)
The infl uence of large-scale mining operations on groundwater quality was investigated in this study. Trace element concentrations in groundwater samples from the North Mara mining area of northern Tanzania were analyzed. ...
Comparative sorption isotherms and removal studies for Pb(II) by physical and thermochemical modification of low-cost agro-wastes from Tanzania
(Elsevier, 2018-03)
Corn and rice husks, agro-wastes available in large quantities in Tanzania, were used to remove Pb2+ from aqueous solution. Husks were used in raw form, pyrolyzed form, and chemically modified form. Material characterization ...
Column design for groundwater hardness removal using cashew nut shells activated carbon with potential application in low-income communities
(2020-01)
tigated.
Water hardness has a significant impact on groundwater, especially in arid and semi-arid
regions, leading to wasted investments in borehole drilling and worsening accessibility to potable
water. In many developing ...
Facile biosynthesis of Ag–ZnO nanocomposites using Launaea cornuta leaf extract and their antimicrobial activity
(NM-AIST, 2013-11-14)
The quest to synthesize safe, non-hazardous Ag–ZnO nanoomposites (NCs) with improved physical and chemical prop-
erties has necessitated green synthesis approaches. In this research, Launaea cornuta leaf extract was ...
Removal of Selected Heavy Metal Ions from Industrial Wastewater Using Rice and Corn Husk Biochar
(Springer Nature Switzerland AG., 2020-05-12)
This study investigated the removal of heavy metal ions from industrial wastewater by using rice and corn husk biochar. The choice of the materials was influenced by their large surface area, abundance of functional groups ...
Analysis of spatio-temporal climate variability of a shallow lake catchment in Tanzania
(IWA Publishing, 2020-04-06)
This study analyzed the trends and spatio-temporal variability in rainfall and temperature, and the length of the rainy season (LRS) in the Lake Manyara catchment, Tanzania, covering a period between 1988 and 2018 using ...
Performance investigation of the slaughterhouse wastewater treatment facility: a case of Mwanza City Slaughterhouse, Tanzania
(Water Practice & Technology, 2020-09-28)
The present study engaged onsite operations and laboratory analysis for Mwanza City Slaughterhouse (MCS)
wastewater to improve the efficiency of wastewater treatment of a newly installed facility. The MCS wastewater
treatment ...
Quantitative assessment of metal contamination and associated pollution risk in sediments from the Mara River in Tanzania
(Springer Nature Switzerland AG., 2020-10-21)
For most rivers in sub-Saharan Africa, information about pollution indices related to sediments is sparse. Sedimentological research of rivers that empty into Lake Victoria is highly patchy and wide apart. The present study ...
