Abstract
Equilibrium and kinetic studies of streptomycin adsorption from aqueous solutions of streptomycin sulphate were carried out using four weakly acidic ion exchange resins: Indion 236 [Ion Exchange (India) Ltd], Amberlite IRC‐50 (Rohm and Haas Co, USA), KB‐2 and KB4‐P2 (both Russian resins), initially in the sodium form. The maximum amounts of streptomycin taken up by the exchangers were about 1640, 1560, 2050 1400 mg g−1 dry resin (sodium form), respectively. The rate of adsorption of the antibiotic was highest with the ion‐exchanger KB‐2, and lowest with KB4‐P2. The initial diffusivity values calculated for the four exchangers at a temperature of 9°C were 2.87 × 10−8, 1.87 × 10−8, 3.42 × 10−8 and 0.468 × 10−8 cm2 s−1, respectively.Keywords
