Cadmium is one of the most hazardous heavy metal contaminants, and it is usually abundant in the wastewater released from paint and pigment industries. Such effluents urgently need to be treated before their proper reuse for various industrial and agricultural purposes. Therefore, in this study, the process of Cd(ii) ion adsorption from waste aqueous-solutions was investigated using polystyrene (PS), ethanolamine-modified polystyrene (EA-PS), and chromium hydroxide-impregnated ethanolamine-modified polystyrene (Cr@EA-PS) as new effective sorbents.

Article Synopsis
  • - Zirconium is a stable radionuclide found in nuclear operations, making its removal from wastewater essential for environmental and human health protection.
  • - A Zn/Al nanostructured layered double hydroxide (Zn/Al-NLDH) was created and tested, demonstrating a strong ability to adsorb zirconium, with a maximum capacity of 117.6 mg/g, and successful desorption using hydrochloric acid.
  • - The adsorption process was characterized as uniform and chemisorptive, fitting well with Langmuir isotherm and Pseudo-second order kinetic models, highlighting the potential of Zn/Al-NLDH as an effective sorbent for water contaminants.

In this research study, recovered carbon black (rCB) was obtained pyrolysis of waste tires. The obtained rCB was then converted into activated carbon species through both chemical treatment and microwave coupled with chemical treatment as a two-step activation process. The activated carbon obtained from chemical activation was denoted as C-AC, while that obtained from exposure to microwave followed by chemical activation was labeled as MC-AC.

Article Synopsis
  • * Researchers utilized Landsat imagery and various indices to analyze LST changes from 2000 to 2021, finding that non-drainage areas experience higher LST values.
  • * Results revealed significant variations in LST over the years and highlighted that land use practices and hydrologic indices significantly influence these temperature changes, with implications for local environmental management.
