Although effective treatment of acid gases such as HCl, SO(x), and NO(x) is essential for preventing air pollution, current methods pose other environmental problems such as CaCl₂ leaching, reduced landfill lifetimes, and solid waste production. Here we show that acid

MgAl-layered double hydroxides with different interlayer anions (nitrate, carbonate and chloride) were evaluated for their abilities to adsorb the organic pesticide glyphosate (N-phosphonomethyl glycine, Gly). The adsorption isotherms of Gly on layered double hydroxides (LDHs) nitrate were described by the
