경유로 인한 농작물 피해를 줄이기 위한 방법으로 톱밥처리 효과를 구명하기 위하여 톱밥의 경유 흡착능과 시용 효과를 상탄(上炭(Muck)), 이탄(泥炭(Peat)) 및 PEAT SORB 등과 비교, 검토한 결과, 흡착제 종류별 경유 제거효율은 톱밥과 PEAT SORB가 토탄 및 이탄에 비해 높았다. 톱밥의 경유 제거효율은 경유에 대한 처리 비율이 1:2(w/v)이상일 때 97% 이상으로 높게 나타났으며, 흡착된 경유의 재용출은 거의 없었다. 경유오염 토양에서의 톱밥 처리효과는 분얼기에 $4,000L{\cdot}ha^{-1}$의 경유를 처리하고 흡착제를 처리하지 않은 구에서는 초장과 엽록소 함량이 대조구에 비해 감소한 반면 톱밥 처리구에서는 생육이 좋았다.

For trying to frontal attack of new solution by fusion of technical tasks and conditions with it's solving methods of the essential tasks of marine resource development and environmental conservation in addition with elements of electronic high-technologies, the magnetic oil spill adsorbent of Mag-Sorbent* has been prepared and proposed to dispose oil spill from the marine disaster for preventing oil pollution by using them and their system with sequentially circular collection of oil spill mag-sorbent powder and fabrics on the electronic equipment like as barge robot for the scheme of sustainable development of environment-friendly technology. Because of recent marine accident occurred at Tae-An cost and earthquake in Sichuan province were very large scale accident of disaster to prevent and manage of them. So, it was verified from the experiment of electronic demonstrator that the skimmer system of oil spill mag-sorbent powder and fabrics prepared was very effective and useful technique to collect oil spill samples on the water surface specially at the closed space of underground cave. At this point, the barge-based electronic remote control was very useful system operating easily on the marine fields but also water level at the small pool to skim it with the environment-friendly system of the disposing marine disaster and preventing oil pollution using magnetic adsorbents of Mag-Sorbent*.

Expanded graphite (EG) was prepared using a drying process for application as an oil-adsorbent: the morphology, expansion volume, and oil absorption capacity of the EG were investigated. The expanded volume of the EG increased with an increasing reaction time and heat treatment temperature. The oil adsorption capacity of the EG was 45 g of n-dodecane per 1 g of EG. It is noted that the drying process of EG is a useful technique for a new oil-adsorbent.

어유의 탈취장치 대신 컬럼에 활성탄, 활성 알루미나, 실리카겔, 대나무 숯 등 흡착제를 단독 혹은 적당한 비율로 혼합하여 충진시켜 탈색과 동시에 탈취시킴으로서 효율적인 탈취효과를 검토하였다. 대멸치유의 탈검효과는 수산 30%를 어유 100 ml에 대하여 18 ml첨가한 것이, 탈산은 수산화 나트륨을 2.5%로 하여 $40^{\circ}C$에서 30분간 처리한 것이 효과적이었다. 탈취의 경우 흡착제(활성탄, 활성알루미나, 실리카겔)를 농도별로 단독 첨가할 경우는 실리카겔30% 첨가가, 그리고 흡착제를 혼합하여 첨가할 경우는 활성알루미나 30%와 실리카겔 10% 혼합 첨가가 가장 우수하였으나 흡착제에 녹차분말 2%를 첨가할 경우 큰 효과가 없었다. 대멸치유의 탈검, 탈산 및 탈취 후의 주요지방산 조성은 16:0, 20:5n-3, 18:1n, 16:1n-7, 22:6n-3 및 18:0이었다. 대멸치 정제유에 $\alpha$-tocopherol를 첨가하여 $25^{\circ}C$에서 40일간 저장시 산화 안정성은 대조구는 20일까지 항산화제를 첨가한 경우는 30일까지라 생각되며 $\alpha$-tocopherol 0.02%첨가보다 0.01% 첨가가 더 효과적이었다.

현 연구의 목적은 변압기 오일에 있는 PCBs의 흡착 제거를 위해 활성탄, 황토, 비산재의 이용 가능성을 탐구하는 것이다. 흡착 실험에서 온도(5, 25, 55), 접촉시간(30분-3일), 흡착제의 양(1, 2.5, 5, 10 g)과 같은 인자들의 영향을 조사하였다. 60분의 흡착평형시간에서 활성탄에 의한 변압기 오일로부터 PCBs의 흡착율이 황토보다 더 우수하였다. 활성탄과 황토의 흡착 평형 데이터는 Freundlich 등온 모델 식에 적합하였다. 5, 25 그리고 $55^{\circ}C$의 온도에서 각 흡착제의 PCBs 흡착 속도상수와 활성화 에너지를 속도 모델을 통하여 알아보았다. 열역학 자료들로부터 변압기 오일/활성탄과 황토 계에서의 PCBs 흡착 공정이 자발적이며 흡열반응이라는 것이 확인되었다.

본 연구에서는 폴리아크릴로니트릴계 탄소나노섬유 스펀지의 제조 및 오일 흡착 거동을 조사하였다. 제조된 탄소나노섬유 스펀지는 물과 기름의 혼합용액에서 우수한 선택적 오일 흡착 능력을 보였으며, 탄소나노섬유 스펀지의 재사용시 흡착 능력도 확인하였다. 또한, 흡착제 내부구조에 정렬된 채널을 형성함으로써, 모세관 현상에 의하여 빠른 오일 흡착 거동을 보이는 탄소나노섬유 스펀지를 제조할 수 있었다. 이후 사용 폐기된 탄소나노섬유 스펀지는 질소 분위기에서 800℃로 열처리하여, 4-아미노페놀의 전기화학적 검출을 위한 센서로의 가능성을 검토하였다.

Mango shell (MS) and mango shell activated carbon (MSAC) was used to adsorb crude oil from water at various experimental conditions. The MSAC was prepared by carbonization at $450^{\circ}C$ and chemical activation using strong $H_3PO_4$ acid. The adsorbents were characterized with Fourier Transform Infrared spectroscopy. Investigations carried out included the effects of parametric variations of different adsorbate dose, adsorbent dose, time, temperature, pH and mixing speed on the adsorption of crude oil. The equilibrium isotherm for the adsorption process was determined using Langmuir, Freundlich, Temkin and Dubinin Radushkevich isotherm models. Temkin isotherm was found to fit the equilibrium data reasonably well than others. The result demonstrated that MSAC was more effective for crude oil adsorption than raw mango shell. Optimum conditions were also presented. The enhanced effect from activation was justified statistically using Analysis of Variance and Bonferroni-Holm Posthoc significance test. The pseudo first order kinetics gave a better fit for crude oil adsorption with both MS and MSAC.
