摘要：

A porous coordination polymer, Co-3(BTC)(2)center dot 12H(2)O (Co-BTC) upon silk yarn, has been synthesized under ultrasound irradiation of identical reaction mixtures of Co(OAc)(2)center dot 2H(2)O and H3BTC (BTC = benzenetricarboxylate) at different conditions. In this work, we successfully loaded compounds with 12 by suspending them in an n-hexane solution of I-2. The delivery of I-2 from compounds in ethanol at room temperature was determined by UV/vis spectroscopy. In the nano-porous materials the surface area is decreased so that the amount of adsorption is decreased a little. So the delivery of iodine from the nano-porous materials can be faster than bulk materials but the amount of adsorbance is less. Effects of temperature, sequential dipping steps and sonication in growth of the Co-BTC upon silk yarn were studied. A comparison of adsorption and desorption rates of iodine between samples under various conditions was also conducted. (C) 2013 Elsevier B.V. All rights reserved.
