Abstract
This work focuses on the adsorptive study of paint effluent coagulation using snail shell coagulant (SSC), in which samples were subjected to physiochemical and instrumental analyses [Fourier transform infrared (FTIR), differential scanning calorimetry/thermo gravimetric analysis (DSC/TGA), scanning electron micrograph (SEM), X-ray diffraction (XRD)]. Nephelometric jar test was also employed and the data generated were subjected to adsorptive kinetic, equilibrium and thermodynamics analyses. 42 % protein was recorded for the snail shell. SEM images and FTIR spectra indicated significant porosity and ammine presence in the SSC. DSC/TGA and XRD indicated samples of high thermal stability and organized crystalline structure, respectively. The data correlated best with Langmuir isotherm with linear regression coefficient (R 2) values >0.9 over the temperatures investigated. Pseudo-second-order kinetic model best described the process at \(K_{2} < 0.05\) (g/mg/min) and R 2 values >0.99. The thermodynamics parameter (\({\Delta G}\), \({\Delta H}\) and \({\Delta S}\)) shows that the process was feasible and spontaneous. The intra-particle diffusion was found to be the rate-limiting step. It could be concluded that while SSC achieved 92 % turbidity removal, the adsorptive component of the process was significant.
