Preliminary performance study of synthetic Alumina nanoparticles for retention of cobalt and cesium cations.

In the present study, a facile nano-sized gamma alumina was synthesized and then examined for immobilization of cobalt and cesium ions individually from aqueous solutions. The comprehensive analysis of functional groups, phase composition, surface morphology and sorption characteristics of the synthesized nano-sized ϒ alumina was executed. It was deduced that acquired material was low-crystalline with a high elimination efficacy towards the concerned cations under slightly alkali and acidic conditions.

Utilization of Modified Attapulgite for the Removal of Sr(II), Co(II), and Ni(II) Ions from Multicomponent System, Part I: Kinetic Studies.

Radionuclide sorption by natural and modified clays is extensively accepted to be an important process from the radioactive waste point of view. This work focused on modification of natural attapulgite with a layered double hydroxide to produce a novel chemisorbent for Sr, Ni, and Co removal from multicomponent solution. The structural and surface characteristics of both attapulgite (ATP) and modified attapulgite (LDH-ATP) were investigated using XRD, FTIR, SEM, and thermal analysis.

Taguchi L optimization approach for simultaneous removal of Cs and Sr ions by a novel scavenger.

This study targeted to investigate the efficacy of a novel nano 2-naphtyl amine6:6-azulene sodium methanesulfonate di sulphonic acid-impregnated zeolite scavenger for simultaneous elimination of Cs and Sr ions from binary aqueous systems. Fractal analysis is introduced to assign a fractal dimension and other fractal characteristics necessary for the surface characterization in terms of fractal dimension (D) and pre-exponential coefficient (C), which, in theory, are independent tool and sole for each surface. It is found that the D value of nano 2-naphtyl amine6:6-azulene sodium methanesulfonate di sulphonic acid-impregnated zeolite of type Y (NAASMS-ZY) is higher than that of nano 2-naphtyl amine6:6-azulene sodium methanesulfonate di sulphonic acid-impregnated zeolite of type X (NAASMS-ZX) and nano 2-naphtyl amine6:6-azulene sodium methanesulfonate di sulphonic acid-impregnated zeolite of type A (NAASMS-ZA) which accordingly, suggests the irregularity of NAASMS-ZY surface and thus demonstrates a large surface area.

Facile radiolabeling optimization process via design of experiments and an intelligent optimization algorithm: Application for omeprazole radioiodination.

The major uses of radiopharmaceuticals (RP) in clinical areas are diagnosis and/or therapy. The present study aimed to utilize the application of fractional factorial design analysis (FFDA) coupled with particle swarm optimization algorithm (PSO) to assess the optimization of RP production process. In this regard, omeprazole (OMP), which is gastric parietal cell proton pump inhibitor (PPI), was radiolabeled with iodine-125 ( I) isotope in order to be used as a radiotracer for stomach imaging.

Optimizing the removal of strontium and cesium ions from binary solutions on magnetic nano-zeolite using response surface methodology (RSM) and artificial neural network (ANN).

The feasibility of using magnetic nano-zeolite (MNZ) to remove cesium and strontium from their binary corrosive solutions was investigated by considering the multi-variant/multi-objective nature of the process. RSM (Response Surface Methodology) and ANN (Artificial Neural Network) were used to model and optimize the removal system and assess sensitive parameters that can affect the process reliability. MNZ is characterized by its high surface area and cation exchange capacity and possesses good regeneration behavior for both elements using citric acid.
