[ 1 ] - استفاده از نانومتخلخل کوکوربیت (6) اوریل به عنوان جاذبی جدید برای حذف رنگ های کنگورد و اریتروسین از اکوسیستمهای آبی
در این تحقیق از نانو متخلخل‌های کوکوربیتوریل به عنوان جاذبی جدید برای حذف رنگ‌های آنیونی از جمله کنگورد و اریتروسین استفاده شد. در این پروژه جهت حذف رنگ‌های آنیونی از اکوسیستمهای آبی، روش ناپیوسته به کار برده شد و به منظور دست‌یابی به حداکثر درصد حذف رنگ‌ها، اثر عواملی مانند میزان اسیدیته محیط، مقدار جاذب و زمان هم زدن نمونه آبی و جاذب مورد بررسی قرار گرفت و بهینه شد. در شرایط بهینه، مطالعه فر...
[ 2 ] - Study on the Application of Cucurbit[6]uril as a Nanoporous Adsorbent for the Removal of 2,4-Dinitrophenol from Wastewaters
In the present study, cucurbit[6]uril was used as a nonporous adsorbent for the removal of 2,4-dinitrophenol from aqueous solutions. The experiments were carried out in a batch system to optimize operation variables such as pH of solution, contact time, adsorbent dose and salt concentration. Langmuir, Freundlich and Tempkin isotherms were applied for the explanation of experimental data. The hi...
[ 3 ] - A Simple and Efficient One-Pot Synthesis of 1,4-Dihydropyridine and Polyhydroquinoline Derivatives Using Phosphosulfonic Acid as a Heterogeneous Catalyst under Solvent-Free Conditions
Phosphosulfonic acid (PSA) was found to be an efficient catalyst for the one-pot three-component Hantzsch condensation reaction of arylaldehydes, ethylacetoacetate and ammonium acetate to afford the corresponding 1,4-dihydropyridine and polyhydroquinoline derivatives in high yields. PSA was also applied for the one-pot preparation of polyhydroquinolines via four-component reaction of a...
[ 4 ] - Synthesis and Characterization of γ-Fe2O3@HAp@β-CD Core-Shell Nanoparticles as a Novel Magnetic Nanoreactor and Its Application in the One-Pot Preparation of β-azido Alcohols, β-nitro Alcohols, and β-cyanohydrins
In this study, β-cyclodextrin(β-CD) supported, hydroxyapatite encapsulated γ-Fe2O3 (γ-Fe2O3@HAp@β-CD) was successfully prepared and evaluated as a solid-liquid phase transfer catalyst and also a molecular host system and nanoreactor for the nucleophilic ring-opening of epoxides in water for the preparation of β-azido alcohols, β-nitro alcohols, an...
