Title: Synthesis and evaluation of a ceramic filter for the removal of tatrazine from waste water
Abstract: Water is increasingly being contaminated with different types (organic and inorganic) contaminants. This has drastically decreased the amount of clean water safe to drink. Anthropogenic activities such as mining and agriculture has contributed meaningfully to the contamination of water mainly because the chemicals used in these activities or their metabolites eventually find their way to human water systems. The occurrence of persistent organic pollutants (POPs) in water has increased in recent years hence more research has been aimed at removing POPs in water. Many techniques have been employed in an effort to remove contaminants from water. These include adsorption, filtration and coagulation and flocculation. This current study aims at removing methyl orange from water using ceramic filters impregnated with biomass (flour). Five ceramic filters of different biomass amount (0,2.5,5,10,30%w/w) were fabricated. The results obtained from the batch experiments showed that the ceramic filter with the highest amount (30%) of biomass (flour) had the highest permeability. The ceramic filter with 30% biomass also achieved highest percentage removal. The FTIR of the ceramic filters showed a number of functional groups present on the filters which help in the adsorption of methyl orange on the ceramic filter. Electrostatic interactions are potentially the interactions present between the ceramic filter and the methyl orange as evidenced by the positive charge available on the ceramic filter (pfzpc) and the negative charge available on the methyl orange.
