Removal of lithium from aqueous solutions by precipitation with sodium and choline alkanoate soaps.

In order to comply with the expected tightening of discharge limits for lithium to surface waters, the lithium-ion battery industry will need access to methods to reduce the concentration of lithium in wastewater down to ppm levels. In this Communication, we discuss the possibility of using sodium and choline soaps as precipitating agents for lithium, comparing the two soap classes and probing the influence of the carbon chain length. It was found that lithium concentrations down to 10 ppm can be reached with sodium stearate, and down to 1 ppm with choline stearate, using a slight excess of the precipitating agent.

Acta Parasitol
January 2025
Department of Medical Laboratory Science, College of Health Sciences, Woldia University, P.O. box 400, Woldia, Ethiopia.
Background: Intestinal parasitic infections are a significant public health concern, especially among food handlers, who can transmit these infections to the public through food preparation and handling. This systematic review and meta-analysis aimed to determine the pooled prevalence and associated factors of intestinal parasitic infections among food handlers in the East African region.
Methods: A systematic review and meta-analysis on intestinal parasitic infections among food handlers involved a comprehensive search across various databases, including Scopus, PubMed, ScienceDirect, Google Scholar, and the institution's library registers.
Efficient biodiesel production from waste cooking oil using a bifunctional Ce/Mn/γ-Al₂O₃ catalysts.
Sci Rep
January 2025
Department of Chemistry, Faculty of Science, Universiti Teknologi Malaysia, 81310, Skudai, Johor Bharu, Malaysia.
As the demand for sustainable energy sources intensifies, biodiesel emerges as a compelling renewable alternative to petroleum-based fuels. Leveraging waste cooking oil (WCO) as a feedstock not only offers an environmentally friendly fuel source but also addresses waste disposal issues. However, biodiesel production from WCO faces challenges, particularly due to its high free fatty acid (FFA) content, which can hinder efficient conversion and lead to soap formation in traditional alkaline-catalysed processes.

Knowledge and practices of parents of school age children towards Helminthiasis and malaria in northwestern Ethiopia.
BMC Public Health
November 2024
Department of Epidemiology, Colledge of Public Health, University of Nebraska Medical Center, Omaha, NE, 68198-4395, USA.
Article Synopsis
- Helminthiasis and malaria are significant health threats in Ethiopia, affecting children's growth and community productivity, necessitating improved knowledge and practices among parents.
- A study involving 398 parents assessed their awareness and behaviors towards these diseases, revealing key insights into sociodemographic factors influencing infection risks in children.
- Results indicated that factors like a mother's gender, household income, and hygiene practices (e.g. washing hands after using the toilet) significantly impacted infection rates, while living conditions, such as latrines and insecticide exposure, also played a crucial role.
