Authors: Thi To Nga Phan  , Thi Hai Nam Chu
Published: July 2023

The aim of this study was to design and characterize a NdFeO3-based photocatalyst prepared by sol-gel method for treatment of oily wastewater. Different characterization techniques such as X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FTIR), UV–vis spectrophometer were used to elucidate the structure, morphology, surface functional groups, and optical absorption properties of the prepared NdFeO3 photocatalyst. The photo-Fenton degradation performance of the as-prepared NdFeO3 photocatalyst was investigated by degrading oily-containing wastewater under visible light irradiation. The NdFeO3 photocatalyst manifests the high chemical oxygen demand (COD) removal efficiency of 97.6 % for 120 min reaction) thanks to its narrow band gap energy and high crystalline degree.
Construction of NdFeO3 nanoparticles on reduced graphene oxide for an enhanced visible light assisted-Fenton degradation of organic pollutant in oily wastewater
Authors: Thi To Nga Phan  , Thi Hai Nam Chu
Published: July 2023

In this study, reduced graphene oxide (rGO) incorporated on NdFeO3  (NFO/rGO) nanocomposite was successfully synthesized by using a facile hydrothermal method for photo-Fenton degradation of phenol in oily wastewater. The structural, elemental, morphological, optical property, and photo-Fenton performance of NFO/rGO nanocomposite were evaluated. From the characterizations, the prepared NFO/rGO nanocomposite showed a heterostructure between reduced graphene oxide (rGO) and NdFeO3. In addition, the prepared NFO/rGO photocatalyst has efficient charge separation compared to that of pure NFO. The photo-Fenton catalytic activity of the NFO/rGO photocatalyst was investigated by phenol degradation under visible light irradiation, with a maximum removal efficiency of 94.3 % after 90 min. In contrast to pure NFO, the introduction of rGO could suggestively enhance the photo-Fenton catalytic activity by increasing the specific surface area and narrow band gap energy. The possible reaction mechanism was also discussed.

Published: July 2023

In this study, adsorptive removal of an antibiotic oxytetracycline (OTC) using polyanion poly(2-acrylamide-2-methylpropane sulfonic acid), PAMPs modified α-Al2O3 nanoparticles (PAMNA) was investigated. Surface modification of α-Al2O3 nanoparticles by PAMPs enhanced the removal efficiency of OTC significantly from 35.5 to 90.7 %. The optimum conditions for adsorptive removal of OTC using PAMNA were found to be pH 4, contact time 120 min and adsorbent dosage 20 mg/mL. Under selected conditions, the removal efficiency of OTC using PAMNA was greater than 90 % while the maximum adsorption capacity reached 140.2 mg/g. After three regenerations, the removal efficiencies of OTC were still higher than 75 %. The results of adsorption isotherms of OTC on PAMNA and the surface charge change of PAMNA indicate that both electrostatic and non-electrostatic interactions control OTC adsorption on PAMNA.

The relationship of sociometric status and self-rating of adolescents with mild mental retardation
Authors: Додзина О.Б.
Published: July 2023

В статье рассматривается влияние специфики общения подростков с умственной отсталостью на развитие их личности, значимое для успешной социализации и социальной интеграции лиц с умственной отсталостью. Цель статьи изучить связь социометрического статуса и уровня самооценки подростков с легкой умственной отсталостью. В исследовании были использованы методики «Социометрия» Дж. Морено и «Исследование самооценки» Дембо-Рубинштейн. Результаты исследования свидетельствуют о наличие связи между социометрическим статусом подростков с умственной отсталостью и уровнем их самооценки. Популярные в коллективе подростки с умственной отсталостью в большинстве случаев имеют адекватный уровень самооценки, а не популярные характеризуются завышенным или заниженным уровнем самооценки. Самооценка у умственно отсталых подростков с высоким социометрическим статусом более реалистична, они лучше понимают себя и окружающих, что и определяет их высокий социометрический статус. Завышенный и особенно заниженный уровни самооценки, отражают общие трудности понимания своей личности и индивидуальности окружающих, что не способствует высокому социометрическому статусу.

This article discusses the impact of the specifics of communication of adolescents with mental retardation on the development of their personality, which is significant for the successful socialization and social integration of people with mental retardation. The purpose of the article is to study the relationship between sociometric status and the level of self-rating of adolescents with mild mental retardation. In the study, the methods "Sociometry" by J. Moreno and "Self-Rating Study" by Dembo-Rubinstein were used. The results of the study indicate the presence of a relationship between the sociometric status of adolescents with mental retardation and their level of self-rating. Adolescents with mental retardation preferred for communication in most cases have an adequate level of self-rating, while those who are rejected are characterized by an overestimated or underestimated level of self-rating. Self-rating of mentally retarded adolescents with high sociometric status is more realistic, they better understand themselves and others, and this determines their high sociometric status. Overestimated and especially underestimated levels of self-rating are a consequence of the difficulty in understanding one's personality and the individuality of others, this does not contribute to a high sociometric status.

The results of this study indicate that students with auditory learning styles based on mathematical representation abilities are able to solve all the questions given. In solving story problems, the subject always writes down what is known and asked first, then answers the problem. Subjects use visual representations in the form of illustrations and tables to make it easier to answer. Next, the subject writes down what is known and asked using verbal and symbolic representations according to what is written on the problem. Auditory subjects solve these problems by involving symbolic representations (mathematical expressions) by substituting them into mathematical formulas. To explain the important part of the problem and write a conclusion at the end of the subject's answer, use a verbal representation in the form of words, sentences, or written text.
