Abstract
|
|
|
LDHs(layered double hydroxides) are of use adsorbent to remove heavy metals, micro-organic pollutants as well as
high concentration of phosphorus from wastewater to low concentration of surface water without pH adjustments. This
study examined the generation condition of LDHs saturated with phosphorus. Less than 20% regeneration rate was
obtained in the absence of alkali and regeneration solution. After the desorption of LDHs with several conditions of
acid and alkali solution, more than 60% of regeneration rate could be expected in the case of using MgCl2 as
regeneration solution.
