In this paper, Mg/Al-layered double hydroxide (Mg/Al-LDH) was modified with the natural polymers sodium alginate and guar gum, and the prepared GG/SA/Mg-Al-LDH composite microsphere adsorbent (G-LDH) showed better adsorption performance for Congo red and hexavalent chromium in aqueous solution than the Mg/Al-LDH. The SEM image of G-LDH shows a distinct micro-spherical morphology, and it can maintain the micro-spherical morphology even after adsorbing Congo Red and hexavalent chromium. G-LDH showed strong adsorption properties for CR (Congo red) and Cr (VI) solutions with initial concentrations of 80 mg L
