Abstract
The search for sustainable alternatives
coagulants has led to the use of plant-derived natural coagulants. This study
investigates the development, characterization, and performance evaluation of
coagulants extracted from piliostigma thonningii seeds for eco-friendly
water purification. Fourier-transform infrared spectroscopy (FTIR) and scanning
electron microscopy (SEM) were employed for characterization, while key
operational parameters including pH, coagulant dosage and settling time were optimized.
Results revealed that the piliostigma thonningii seed coagulant achieved
a turbidity removal efficiency of 91.6% at optimal conditions of pH 7 and 150
mg/L dosage. The FTIR spectra gave characteristic at 3432 cm⁻¹ (O–H and N–H
stretching), 1649 cm⁻¹ (C=O stretching of amide), and 1052 cm⁻¹ (C–O
stretching) this confirmed the presence of amine, hydroxyl, and carboxyl
functional groups associated with coagulation, while SEM showed a porous
morphology suitable for adsorption. The coagulant demonstrated high removal of
suspended solids (92%), color (85%), and heavy metals (Pb, Cd, Cr up to 78%).
Biodegradability and toxicity assessments confirmed its environmental safety.
The findings establish piliostigma thonningii seeds as a viable, less
cost-effective, and sustainable natural coagulant for water purification.
