A hybrid adsorbent was prepared in bulk by immobilizing copper onto commercially available natural chitosan as the polymeric matrix for selective removal of phosphate from a reservoir that was severely affected by algae bloom. The batch test showed ∼35 mg g−1 as P sorption capacity for phosphate and the laboratory scale column test for synthetic wastewater yielded the following affinity order: phosphate > sulfate > nitrate. The field-scale adsorption test showed that the effluent T-P satisfied the 0.2 mg L−1 standard. Overall results insinuate that the hybrid adsorbent can be considered as a promising candidate for efficient phosphate removal materials.

디지털 시대에는 누구나 쉽게 정보에 접근 할 수가 있어 아주 간단하게 다른 사람의 정보를 불법 복제해서 무단으로 사용하는 경우가 증가하게 되었다. 이는 많은 투자와 노력으로 지식을 생성하는 일도 중요하지만 이를 관리하고 보호하는 일이 중요한 과제로 부상하고 있다는 것을 의미한다. 본 논문에서는 다른 사람의 지적 재산권을 침해하고 표절을 하여 사용했을 경우 이를 효과적으로 탐지하는 새로운 방법과 이론을 제시하고자 한다.

Cu(II) can cause health problem for human being and phosphate is a key pollutant induces eutrophication in rivers and ponds. To remove of Cu(II) and phosphate from solution, chitosan as adsorbent was chosen and used as a form of hydrogel bead. Due to the chemical instability of hydrogel chitosan bead (HCB), the crosslinked HCB by glutaraldehyde (GA) was prepared (HCB-G). HCB-G maintained the spherical bead type at 1% HCl without a loss of chitosan. A variety of batch experiment tests were carried out to determine the removal efficiency (%), maximum uptake (Q, mg/g), and reaction rate. In the single presence of Cu(II) or phosphate, the removal efficiency was obtained to 17 and 16%, respectively. However, the removal efficiency of Cu(II) and phosphate was increased to 50~55% at a mixed solution. The maximum uptake (Q) for Cu(II) and phosphate was enhanced from 11.3 to74.4 mg/g and from 3.34 to 36.6 mg/g, respectively. While the reaction rate of Cu(II) and phosphate was almost finished within 24 and 6 h at single solution, it was not changed for Cu(II) but was retarded for phosphate at mixed solution.
