The Removal of Arsenic and Its Inorganic Forms from Marine Algae—A Base for Inexpensive and Efficient Fertilizers

“…Bioavailable inorganic As species present in macroalgae-based organic fertilizers can easily migrate to the soil and crop plants and enter the food/feed chain, increasing the human/animal exposure risk of toxic As species. This problem can be solved by the aqueous extraction of inorganic As species from macroalgae before their application as an organic fertilizer component with the simultaneous efficient adsorption of As(V)/As(III) from aqueous extracts by the porous solid, such as cerium oxide [ 3 , 4 , 8 ].…”

Nitrogen-doped carbon dots/Fe3+-based fluorescent probe for the “off–on” sensing of As(v) in seafood

“…To date, various detection techniques have been successfully developed to determine inorganic arsenic, such as atomic absorption spectroscopy (AAS), 7 hydride generation atomic fluorescence spectrometry (HG-AFS), 8 anodic stripping voltammetry (SWASV-CV), 9 surface-enhanced Raman scattering, 10 and inductively coupled plasma mass spectrometry (ICP-MS). 11 Although these methods possess good sensitivity and high accuracy, they still appear to have some disadvantages, such as high cost, dependence on sophisticated equipment, time-consuming, and requirement of intricate sample pretreatment, which limit their extensive application.…”
