Preparation of some resorcinol formaldehyde resins for the separation of super(134)CS from acidic waste streams

An assortment of equilibrium assessments was conducted at 298+ or -2K with a granulated resorcinol-formaldehyde (RF) resin, and acetone resorcinol formaldehyde gel (ARF) in an attempt to decontaminate super(134)CS from waste streams. A: R: F: Na sub(2)Co sub(3) was optimized as 2:1:2:1.6, during ARF preparation while, R: F: Na sub(2)Co sub(3) was found to be 1: 3.5: 1.5 in case of RF, respectively. The obtained gels were amorphous and possessed different functional groups. The ARF had higher surface area and total pore volume values than RF; 780 m super(2)/g and 0.62 cm super(3)/g were the maximum values obtained for ARF under different conditions. The scanning electron microscope graphs proved that they are granular and spherical in nature with nanometer- sizes under 22 W ultrasonic dispersion. In these tryouts, simulated waste sample to super(134)Cs was used in comparison with other radioactive super(60)Co and super(152+154). Lagergren first-order kinetic model was used to compare the kinetic constants, K sub(ads) of the tested ions; the order of K sub(ads) of Cs super(+) < Co super(2+) < Eu super(3+), which were in accordance with data obtained in the Cartesian coordinate in space. However, a reversed order of selectivity and capacity measurements was obtained because of hydration of the ions in solution.
