| چکیده | ||
| In this research poly (Styrene–Alternative-Maleic Anhydride) (SMA) and derivations of SMA with Melamine, (Melamine + 1,2 Diamino Ethane) and (Melamine + 1,3 Diamino Propane) CSMA-M, CSMA-ME and CSMA-MP were synthesized, respectively. This method is very simple, cheap, precise and used polymers recyclable to seven terms. The purpose of the present work was exploring the adsorption power of CSMA-M and its derived polymer to removed silver(I) ions from aqueous solution. In this research, batch adsorption tests were exhibited and the effect of different parameters on this removal process has been studied. The effects of pH, adsorption time, metal ion concentration and the acidic remedy on the adsorption process were optimized. The optimum pH for adsorption was found to be 6.0. In adsorption explores, remained Ag+ concentration arrives equilibrium in a short duration of 60 min. Maximum adsorption capacity, 67.57, 76.90 and 95.24 mg Ag+/g polymer CSMA-M, SMA–ME and SMA–MP respectively.showed that this adsorbents were appropriate for removing silver(I) from aqueous solution. The resins were characterized by Fourier transform Infra Red(FT-IR) spectroscopy, Scanning Electron Microscopy (SEM), X-ray diffraction(XRD) and Differential Scanning Calorimetry (DSC), (Thermo Gravimetric Analysis) TGA analysis. | ||

| چکیده [English] | ||
| در این تحقیق پلی استایرن–آلترناتیو-مالئیک انیدرید و مشتقاتی از آن باملامین و ملامین و1،2دی آمینواتان و1،3 دی آمینوپروپان به ترتیب سنتز شدهاند. این روش یک روش بسیار ساده، ارزان، دقیق و پلیمرهای بکار رفته توانایی هفت بار بازگردانی را دارند. در این پژوهش قدرت جذب پلی استایرن–آلترناتیو-مالئیک انیدرید-ملامین ومشتقات آن برای حذف یونهای نقره از محلولهای آبی مورد بررسی قرار گرفته و این جاذبها برای این کار پیشنهاد شدهاند. دراین تحقیق اثر هر یک از پارامترهای مختلف مؤثر بر جاذب در فرآیند حذف یونهای نقره مورد مطالعه و بررسی قرار گرفته و اثر هر یک از آنها بهینه شده است (نظیر زمان جذب، زمان تماس، مقدار جاذب، سرعت چرخش شیکر). بیشترین حذف یون نقره در 6= pH اتفاق افتاده است و زمان تماس بهینه برای یونهای نقره 60 دقیقه است. بیشترین ظرفیت جذب CSMA-MP, CSMA-ME, CSMA-M به ترتیب برابر 67.57، 76.90 و 95.24 بوده است. چنانچه مشخص شده است این جاذبها برای حذف یونهای نقره از محلولهای آبی مناسب میباشند. این رزینها بوسیله آنالیز FT-IR, SEM, XRD, DSC, TGA مشخص شده اند. | ||
