Abstract:

Depending on industrial developments, the concentration of bor compounds used in many industries and surface waters is increasing. Therefore, bor removal is very important in terms of both human health and healthy agricultural products. In this study, the adsorption capacity of the cranberries is studied. For the study, the effect of the solution's pH on the adsorption process, the concentrations of cranberries and the time of contact was assessed below a fixed mixing rate (150 rpm) and temperature (20 0C). It is also defined by the use of cortex, scanned electron microscope, X-ray fluorescence and Fourier conversion infrared techniques. The obtained experimental data were analyzed using different isotherms and kinetic models in the cutting process. The optimal conditions for the adsorption process are determined as the adsorbent dose = 2 g/L, pH = 5.13 and contact time = 5 minutes. The maximum bor cleansing efficiency of the cranberries is achieved at approximately 88% in ideal conditions. The maximum adsorption capacity based on Langmuir isotherm is 12.61 mg/g, and the adsorption of the bor element on the cortex core is defined by false second degree kinetics. As a result, it has been recorded that the bor element can be effectively removed from the water solution by using the cranberry leather.
