In the phosphorus experiments, conducted under sterile conditions, the samples were subject to phosphorus solutions. Concentrations of phosphorus solution were between 0.081 mmol/L and 3.2 mmol/L, and the pH values were 4 and 11. In the calcium experiments, the calcium-retained samples were subject to the calcium solutions under the constant pH conditions. Concentrations of the calcium solution were 0 mmol/L and 2.5 mmol/L, and the pH values for these solutions were 4, 8, and 11. The results are as follows; phosphorus adsorption was attributed to both pH and phosphorus concentration. The amount of phosphorus adsorption tends to be large at a low pH or at high phosphorus concentrations. The release of calcium from the samples was attributed to both pH and calcium concentration, and the amount of released calcium tends to be large at a low pH or at low calcium concentrations., 原著論文}, pages = {65--72}, title = {板状木節粘土によるリン除去とカルシウム放出}, volume = {31}, year = {2004}, yomi = {コンドウ, マサアキ} }
