The present study aims to investigate novel ultrasonic synthesized MIL-53(Al) and its applications in adsorption. Both conventional and ultrasonic methods were used to synthesized Mil-53(Al). The ultrasonic-assisted synthesis procedure results in reducing synthesis time to 24 hours; however, Compared to that conventional method takes 3 days to create the framework. Applying ultrasonic waves also increases surface area to 50% more than the ones synthesized by the conventional method, as well as creating the hierarchical MIL-53(Al) structure (meso- and micro-) pores. To this end, XRD, FESEM, BET, and FTIR analyses were employed to identify and characterize MIL-53(Al). The unique structure and high MIL-53(Al) yield lead to effective adsorption among MOF and lead ions. The optimum conditions for removing lead were 6.0 pH, 20 mg/l concentration, 60.0 min contact time, 0.04g adsorbent dose, and 318k temperature with 97.63% removal of the lead ions. The experimental adsorption equilibrium and kinetic data fitted the Langmuir isotherm and pseudo-second-order kinetic models, respectively. Moreover, the use of ultrasonic synthesized MIL-53(Al), for the first time as a novel adsorbent in heavy metal removal, pointed to the great potential of this new environmentally-friendly adsorbent in removing lead ions from aqueous solutions.

Accumulation and health risk assessment of cobalt (Co), antimony (Sb), vanadium (V), and lanthanum (La) in tomatoes growing in an area contaminated with municipal wastewater were investigated. For this aim, tomatoe samples were taken and sepertaed into root, stem and leaf parts. Co, Sb, V and La concentrations were detected in plant organs. The arrangement of the elements in the root, stem, and leaf of ripe and unripe tomatoes was V>Co>La>Sb. According to total element values in the ripe and unripe tomatoes; the highest values were 23±1.1 mg/kg and 35±1.7 mg/kg for V, respectively. Co, Sb, V, and La values accumulated by ripe and unripe tomatoes were determined as 24.65 and 25.6 times for Co, 1.8 and 2.7 times for Sb, 46 and 70 times for V and 4.4 and 6.15 times for La, respectively when compared with control. Total Co, Sb, V, and La were male

The present study aims at investigating sonochemically synthesized MIL-53(Al) and its applications in adsorption lead ions from aqueous solution. XRD, FESEM, BET, and FTIR analyses were employed to identify and characterize MIL-53(Al). The ultrasonic-assisted synthesis procedure results in reducing the synthesis time to 24 h; however, the conventional synthesis of MIL-53(Al) takes 3 days. Applying ultrasonic waves also leads to increase of the specific surface area up to 50% more than that of synthesized by the conventional method, as well as creating the hierarchical MIL-53(Al) structure which reduces the mass transfer limitation of ions into internal micropores. The optimum conditions for removing lead ions are pH of 6, Pb+2 ion concentration of 20 mg/L, contact time of 60 min, adsorbent dose of 0.04 g, and temperature of 318 K with the removal efficiency of 97.63%. The experimental adsorption equilibrium and kinetic data fit the Langmuir isotherm and pseudo-second-order kinetic models, respectively. Moreover, the usage of sonochemically synthesized MIL-53(Al), for the first time as an adsorbent in heavy metal removal points to the great potential of this new environmentally-friendly adsorbent in removing lead ions from aqueous solutions
