dc.description.abstractThe present article describes As(III) sorption behavior of novel calix[4]arene appended TS-4 resin. The sorption ability of TS-4 resin has been evaluated at wide range of pH, i.e., pH 214. The maximum As(III) sorption efficiency (95%) was achieved at pH 2, which shows that the TS-4 resin possesses greater affinity for As(III) at this pH. Column sorption mechanism was evaluated through various operating parameters, i.e., change in concentration, flow rate, bed heights, and pH. The experimental data were also tested against bed depth service time model and from the results; it has been observed that the data is in close agreement with the theoretically calculated values. Thus, from the data it has been revealed that TS-4 resin has maximum column efficiency of 0.13mmolg1. Application of TS-4 to real samples indicates a slight decrease (23%) in extraction efficiency of TS-4 because of high concentration of total dissolved salts. Thermal behavior was tested by differential scanning calorimetry and it has been observed that TS-4 resin is stable up to 160 degrees C. TS-4 resin was found to be regenerable and best regeneration was achieved by using 4% solution of NaOH. It can be deduced from the study that the resin will find its applicability in small as well as industrial scale water purification plants.en_US
