“…The mass transfer diffusion models were considered for the understanding of feasible diffusion mechanisms in the adsorption of selected antibiotics mixture on the DRPAC developed. The Weber Morris Intraparticle diffusion model involves pore diffusion where adsorbate molecules percolate into the interior of adsorbent particles and are used to estimate and determine the rate of the adsorption process (Supriyadi et al 2019). The Matthew-Weber transfer diffusion model is used to examine the external mass transfer on the boundary phase around the adsorbent understudy (Supriyadi et al 2019).…”

“…The basic principle behind the rate of adsorption mechanisms involves the search for the best model that best fits the data generated. Consequently, some important variables such as equilibrium time, mechanism of adsorption and the rate-determining step can be determined (Supriyadi et al 2019). However, the main objective of this study was to examine the transfer mechanism that occurs in the adsorption of a mixture of pollutants, particularly antibiotics mixture (amoxicillin ampicillin and tetracycline), which are involved in a competition for the available surface and pore of the adsorbent.…”

The selection of suitable mass transfer models that fit the adsorption of a mixture of antibiotics in aqueous solution onto activated carbon derived from Delonix Regia Pods (DRPs) was examined in this study. The ripe DRPs were cleaned, activated with KOH and then carbonised at 350 °C. The surface chemistry of the raw and the modified DRPs were characterised using Fourier Transform Infrared (FTIR), before being subjected to batch adsorption of a mixture of Amoxicillin (AMO), Tetracycline (TETRA) and Ampicillin (AMP) under the effect of time (0-240 mins), and concentration (20-100 mg/l). The adsorption diffusion mechanisms of the process were analyzed. The spectra of the raw and modified DRP indicate the existence of hydroxyl groups alkanes, unconjugated ketone, carbonyl, and ester groups. McKay has the highest (0.9445) for the mass transfer diffusion model. This indicates that the adsorption rate of the selected antibiotics in the wastewater is regulated and monitored by the internal mass transport processes in accordance with a pore diffusion mechanism.

Antibiotics release has been identified as a series concern with adverse effects on the ecosystem. Nano-adsorbents are promising materials to remove antibiotics from wastewater effluents. In this work, iron-trimesic metal organic frameworks (Fe-BTC MOF) was synthesized and characterized by XRD, FTIR, SEM and TEM. Fe-BTC was then investigated as nanoadsorbent for tetracycline (TC) and Ceftriaxone sodium (CFTR) antibiotics. TC and CFTR are common antibiotics, which are extensively used by industrial activities and thereby are released to wastewater effluents. Fe-BTC MOF showed high adsorption capacity of 713 and 1284.6 mg/g for TC and CFTR respectively. This study aims to compares the uptake efficiencies for two drug residues. Single antibiotic residues adsorption tests showed that Fe-BTC MOF effectively takes up TC more than CFTR. The influence of pH, dose, concentration and time on the adsorption process was estimated. Such adsorption capacity of Fe-BTC will make it favorable for further environmental applications.
