Dual phase zirconium-based metal-organic gel (Zr-MOG) as chromium (VI) removal via photoreduction / Anis Muneerah Shaiful Bahari ... [et al.]

Given the widespread production of Cr(VI) from numerous industrial processes, as well as its harmful toxicity as a carcinogenic agent, it is critical to explore stable and efficient adsorbents with quick performance for Cr(VI). Recently, environmentally friendly adsorbents have been employed to redu...
