Three low-cost adsorbents (purified raw attapulgite (A-ATP). high-temperature-calcined attapulgite (T-ATP). and hydrothermal loading of MgO (MgO-ATP)) were prepared as adsorbents for the removal of Cd(II) and Pb(II). By evaluating the effect of the initial solution pH. https://www.marcelovicente.com/product-category/nano-wax/
