Fabrication and characterization of a magnetite water hyacinth nanocomposite for effective Cr(VI) remediation.

Exploring a method for purifying water, this study focused on using a novel biosorbent a nanocomposite made by combining magnetite with water hyacinth - to capture and remove toxic hexavalent chromium (Cr(VI)). The synthesized material underwent thorough examination using techniques like FTIR to identify its surface chemistry, revealing the presence of hydroxyl and carbonyl groups, which likely play a crucial role in binding Cr(VI). The material's surface charge, indicated by a PZC of 5.

Removal of methylene blue dye from textile industry wastewater using green synthesized Teff straw assisted ZnO nanoparticle.

Methylene blue dye contamination poses serious environmental and health risks, necessitating efficient removal methods. Conventional Zinc Oxide (ZnO) nanoparticles synthesized chemically face issues like toxicity, instability, and agglomeration, reducing their effectiveness. This study explores the green synthesis, characterization, and application of teff straw-assisted ZnO nanoparticles, using neem leaf extract as a capping agent, for MBD removal from textile wastewater.

Aloe vera leaf extract as a sustainable route for silver nanoparticle synthesis with enhanced antimicrobial activity.

This study shows how to easily make silver nanoparticles (AgNPs) using Aloe vera leaf extract a simple and green approach. This method offers a biocompatible, economical, and environmentally friendly method without hazardous chemicals. A central composite design (CCD) was used to find the best way to make nanoparticles, adjusting the amount of AgNO, the pH, and the incubation time to see how they all worked together.

The potential of polyethylene microplastics to transport copper in aquatic systems: Adsorption and desorption studies.

Heavy metals and microplastics are two types of general contaminants that can cause significant damage to water systems and organisms. However, the interaction of heavy metal ions with microplastic in aquatic systems received less attention compared with that of organic contaminants. This study aims to explore the interaction of copper (II) ions with microplastic (polyethylene) in aquatic systems.

Analysis of chemical engineering curriculum to improve process safety competency.

Continuous process safety (PS) development is the key to maintaining a good PS system, and its competency plays a substantial role. However, PS incompetency can still be demonstrated in several process-related accidents, particularly major catastrophic incidents. To mitigate this gap, universities' PS education is analysed.

Addressing process safety challenges in downstream industries in Brunei Darussalam.

International oil and gas corporations operating in Brunei may apply process safety management (PSM) and analysis techniques, resulting in varying approaches and measures to address process safety issues. Global corporations may have developed their own process safety standards while smaller firms employ established ones. This research compares the local PSM systems and standards with international ones to determine which employers face the most difficulties in implementing or increasing process safety inside their organizations.

Synthesis of green marine algal-based biochar for remediation of arsenic(V) from contaminated waters in batch and column mode of operation.

The sorption behavior of biochar derived from green seaweed () toward arsenic(V) ions was explored in both batch and continuous modes. The pH edge experiments indicated optimum arsenic(V) sorption observed at pH 4, with maximum sorptional capacity of 7.67 mg/g through isotherm experiments.
