Pb2+ adsorption onto a soil by irrigation of sewage in the Pearl River Delta of South China was examined as a function of the reaction time, solution pH, initial lead concentration, organic matter (humic acid) and competitive ions (Cu2+). The adsorption of Pb2+ onto the soil was investigated on batch equilibrium adsorption experiments. Results show that the Pb2+ adsorption on the soil is relatively...
The research chose the alginate sodium and PVA as the materials to immobilize the atrazine degrading bacteria. Four methods were adopted: alginate sodium adsorption method, alginate sodium embedding method, PVA boric cross linking method and PVA freezing method. The degrading effects and the characteristics of the atrazine degrading bacteria in the two materials were studied respectively. The result...
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...
Put dead immobilized saccharomyces cerevisiae biomass into column of continuous upflowing reactor. Study the influence of temperature, quantity of saccharomyces cerevisiae in column and initial Cu2+ concentration on Cu2+ adsorption. Determine optimal operating parameters of initial pH values, flow rates and quantities of saccharomyces cerevisiae in column through orthogonal experiment. Analyse adsorption...
