The deciduous ginkgo leaves were used as adsorbent to absorb the copper in wastewater.The effects of adsorption time,dosage,copper concentration,pH,temperature and size were investigated.The results showed that the adsorption removal rate can reach almost 100% as the adsorbent size was 150-180μm,the dosage was 1.3 t0 1.6g,the temperature was 25 to 50℃,the initial concentration of copper was less than 40mg/L.The adsorption process agreed well with the pseudo first order kinetics.
