Adsorption of silica from aqueous solution onto magnesium oxide nanoparticle: kinetic and equilibrium studies
Nahied Shahbodaghi, Daryoush Afzali, Maryam Fayazi,
Volume 15, Issue 1 (4-2022)
Abstract
Background and Objective: With increasing water pollution, serious water shortages and increased pressure to save water, recycling and reuse of water has attracted more attention in various industries. Removal of silica from cooling water is essential for recycling and reuse of water. The aim of this study was to remove silica from water using magnesium oxide nanoparticles (MgO) synthesized by chemical deposition method.
Materials and Methods: Synthetic nanoparticles were successfully determined using field emission scanning electron microscopy (FE-SEM), Fourier transform infrared (FTIR) and X-ray diffraction (XRD). To determine the optimal adsorption conditions the batch system, the effect of important parameters such as pH (2-8), contact time (0-150 min), initial concentration of silica solution (50-1000 mg/L), adsorbent amount (0.01-0.14 g) and temperature (25-60 ˚C) were studied.
Results: Under optimal conditions, an almost removal of 200 mg/L silica solution was achieved in 60 min reaction time. Equilibrium data were analyzed using the Langmuir and Freundlich isotherms. The adsorption process can be well described by the Langmuir model, and the maximum adsorption capacity was calculated as 75.76 mg/g. Synthetic data were analyzed using pseudo-first-order and pseudo-second-order equations. The pseudo-second-order model showed good agreement with the obtained data (R2 = 0.9949).
Conclusion: Due to the high potential of magnesium oxide nanoparticles in silica removal, it can be a good candidate for the removal of silica and industrial wastewater treatment.

Volume 15, Issue 4 (3-2023)
Abstract
Background and Objective: Due to the presence of infectious diseases and parasitic contamination in kindergartens, it is very important to observe the health points in these centers. This cross-sectional analytical study was conducted to investigate the environmental health status of Saveh kindergartens in 2020.
Materials and Methods: A checklist with 133 questions was designed, including 57 questions specific to the conditions of the coronavirus, taken from the instructions for the second step of the fight against the coronavirus and 76 questions from regulation 150/920318. All active kindergartens (9 cases) in the study were included, and the answers to the questions as yes, no, and not applicable were recorded and using SPSS software, independent T, chi-square, and one-way ANOVA was analyzed.
Results: The results obtained from the analysis of the checklist showed that the compliance of the health status of all kinds of kindergartens with the regulations of 150/920318 has a percentage of total desirability that includes personal hygiene (81/4%), food hygiene (63%), tools and equipment hygiene (66/5%), building hygiene (78%), health education (90%), considerations regarding disinfectants and disinfectants based on alcohol (92%) and considerations regarding bleaches (94%). There was no significant relationship between the per capita of each child and the different items on the checklist (p>0/05).
Conclusion: This study showed that the general environmental health status of kindergartens in Saveh was favorable and only two variables of hygiene of tools and equipment (66/5%) and food hygiene (63%) were the least desirable among the studied factors that should be considered.

Prevalence of enterobius vermicularis (Pinworm) infection in Iranian kindergartens: a systematic review
Mohadeseh Bodaghi, Tayebeh Rasolevandi, Hossein Azarpira,
Volume 18, Issue 4 (3-2026)
Abstract
Background and Objective: Parasitic infections are major public health challenges in children, particularly in group settings such as kindergartens, where conditions for transmission are more favorable. Enterobius vermicularis (pinworm) is one of the most common causes of intestinal infections in this age group. This study was conducted to investigate the prevalence of Enterobius infection and associated factors in kindergartens across Iran.
Materials and Methods: In this systematic review, articles published up to the end of January 2025 were retrieved from the following databases: Google Scholar, SID, Magiran, Irandoc, Web of Science, PubMed, and Scopus using the keywords: “Enterobiasis,” “Enterobius vermicularis,” “Oxyuriasis,” “Oxyur,” “Intestinal infection,” “Intestinal parasite,” “Prevalence,” “Children,” “Elementary schools,” “Preschool centers,” “Kindergarten,” and “Iran.” Out of a total of 1116 identified articles, 707 were excluded after reviewing the title and abstract, and 333 were removed due to duplication. Ultimately, 76 articles were selected for full-text evaluation, from which 24 studies related to the prevalence of Enterobius in Iranian kindergartens were included in the final analysis.
Results: Of the 24 studies reviewed, 23 were conducted using questionnaires, and one study utilized interviews. The total sample size across these studies was 13.567 children, and the average prevalence of Enterobius infection was estimated at 14.90 percentage.
Conclusion: Despite relative improvements in hygiene conditions, the prevalence of Enterobius infection in some kindergartens remains concerning. The role of active transmission pathways and their association with children's demographic factors highlights the importance of timely identification and intervention. Implementing targeted educational programs for parents and kindergarten staff, along with coordinated preventive measures, is essential to control the spread of this parasite.
