The paper investigated the treatment effect of modified rice husk as an adsorbent on wastewater containing Zn(II). Langmuir and Freundlich equations quantified the Zn(II) removal effect of modified rice husk. We analyzed characteristics of adsorption kinetics, the initial pH value, temperature effect on adsorption process, and compared with the regeneration efficiency of adsorbent. The results showed...
Making use of jujube kernel as the main material, jujube kernel activated carbon was prepared with a microwave-induced activation process using phosphoric acid and zinc chloride as the activating agent. The effects of various factors such as microwave power, radiation time, activation agent/carbon ratio and activation agent concentration on the activation have been studied. Experimental results indicated...
On basis of chemical extraction technology, H3PO4 has been used to remove heavy metals from the industrial sewage sludge. At the laboratory scale, heavy metals Zn, Pb, Cd, Ni, Cr and Cu were extracted synchronously from the sewage sludge. The results showed that H3PO4 concentrations had a significant effect on the extraction efficiency of heavy metals. The extraction efficiency increased gradually...
