Application


  • Rapid assessment of soil accessible Cr(Ⅵ) in the field by a portable RGB color sensor.: This study details the use of a portable RGB color sensor for quick field assessment of Cr(VI) in soil, aiming to improve environmental monitoring techniques (Guo et al., 2024).


  • Immobilization of diphenylcarbazide on paper-based analytical devices for the pre-concentration and detection of chromium VI in water samples.: This paper introduces a method for immobilizing diphenylcarbazide on paper-based analytical devices, enhancing the detection and pre-concentration of Cr(VI) in water, thus facilitating better environmental analysis (Ben Jaballah et al., 2023).


  • Tailoring Acid Free-Paper based Analytical Devices (Af-PADs) via radiation assisted modification of cellulose paper.: The study explores the modification of cellulose paper through radiation to create acid-free paper-based analytical devices (Af-PADs) for enhanced analytical performance in chemical sensing (Rawat et al., 2023).


  • Water Decontamination from Cr(VI) by Transparent Silica Xerogel Monolith.: This research presents a novel transparent silica xerogel monolith for efficient decontamination of Cr(VI) from water, offering a new approach to water purification technologies (Zannotti et al., 2023).
