Abstract
In this research, behaviour of turbidity and phosphorus in water and soil dependent upon pH and a change of water was studied. Phosphorus dissolve rate from turbidity was increased for water if potential of hydrogen was less than pH 4 or more than pH 7. Turbidity release rate from soil was increased with pH. Turbidity release rate from soil was drastically increased for water if potential of hydrogen was more than pH 4. turbidity release rate from soil was stabilized more than pH 6. Dissolved phosphorus was increased from 2 hours to 24 hours and stabilized in 24 hours. Turbidity was reached the peak of 24 hours and decreased from 24 hours to 96 hours. Turbidity and dissolved phosphorus was decreased for water if these samples were changed a overlying water. Behaviour of turbidity was analogous to dissolved phosphorus when potential of hydrogen was increased from pH 6 to pH 10 and a change of overlying water was increased from 1 time to 4 times. These results suggest that phosphorus dissolve rate and turbidity were directiy correlated with pH. These results are of great importance in lakes because most lakes have a pH in the range of pH 7-10.
본 연구는 물과 토양에서 pH와 상등액을 변화 시켜었을 때 인과 탁도의 행태에 관해 연구 하였다. 탁도의 인 용출율은 pH 4 이하 또는 pH 7 이상일 때 증가 되었고, 토양으로 부터 탁도 발생율은 pH가 증가하면 증가하며, pH 4 보다 커지면 급격히 상승한 후 pH 6 이상에서 안정화된다. 용존성인은 2-24시간까지 증가 후 안정화 됐고, 탁도 역시 24 시간까지 정점에 도달한 후 96시간까지 감소됨. 시료상 등수를 교체를 하면 용존성인과 탁도는 감소한다. 시료를 pH 6에서 pH 10으로 증가시키고, 상등액 교체를 1회에서 4회로 동시에 증가시킬 때 용존성인과 탁도의 행태는 유사하다. 이 결과로 용존성인과 탁도는 pH와 직접적인 연관이 있다고 사료되며, 호수는 pH 7-10 정도이기 때문에 이 결과는 대단히 중요하다.
