In-situ synthesis of calcium/magnesium phosphate system for water de-fluoridation: Clay ceramic materials
(Elsevier, 2022-02-15)Clay ceramic water filters impregnated with silver colloids have been used to purify water in many parts of East Africa disregarding the removal of fluoride, which is a health-threatening ion in water supplies. This paper ... -
What influences individuals to invest in improved sanitation services and hygiene behaviours in a small town? A formative research study in Babati, Tanzania
(PLOS ONE, 2022-07-21)Sub-Sahara African countries face immense challenges in ensuring adequate sanitation and hygiene behaviours to the rapidly growing populations. Attempts to address these challenges require empirical evidence to inform ... -
Photocatalytic degradation of azo dyes in textile wastewater by Polyaniline composite catalyst-a review
(Elsevier B.V., 2022-09)Azo dyes in industrial textile and dye effluent (5–30%) have become irresistibly recalcitrant and toxic to both treatments and the environment respectively. Global concerns about the persistent nature of these dyes and the ... -
Remediation of Soils Contaminated by Fluoride Using a Fermentation Product of Seaweed (Eucheuma cottonii)
(Hindawi, 2022-10-03)is study investigated the e cacy of fermented seaweed (Eucheuma cottonii) on the remediation of uoride-contaminated soil. e soil was amended with either 1.25, 3.0, or 5.0% (w/w) fermented seaweed (FSW), parallel with ... -
Water Boiling Test of carbonized briquettes produced from charcoal fines using African Elemi (Canarium schweinfurthii) resin as an organic binder
(Springer Nature Switzerland AG., 2021-10-10)The study evaluated carbonized briquettes produced from charcoal fines using African Elemi (Canarium schweinfurthii) resin as a binder. Briquette samples (B25, B30, B35, B40) with the ratio of charcoal fines:binder of 3:1, ... -
Production of carbonized briquettes from charcoal fines using African Elemi (Canarium Schweinfurthii) resin as an organic binder
(Taylor & Francis Group, 2021-09-25)This study investigated the use of African Elemi (Canarium Schweinfurthii) resin as a binder for the production of carbonized briquettes from charcoal fines. The binder and charcoal fines were characterized through proximate ... -
