Abstract
Due to the abundance of sulphur found in soil under Aerobic condition the main element is being absorbed by the plant and it is brought from three major sources weathered they compose organic matter and atmospheric precipitation. Modified clay is suitable absorbent for the removal of sulphate from contaminated water in terms of natural and commercial absorbent. The maximum sulphate was found to be 119mg/L and 13mg/L for modified and unmodified clay at pH of 7.5 in three hours with 580mg/L of initial concentration.
Highlights
Sulphate is the most abundant form of sulfur found in soils under aerobic conditions and the main ionic species of this element that is absorbed by plants
It was noted that the significant decrease in the atmospheric emission of acidic reagents reached in some economically developed countries does not always result in an expected increase in the soil pH and a decrease in the sulfate concentration in the soil solution [3]
It is well recognized that the adsorption of sulphate by soils and soil materials occurs by replacement of M-OH or M-OH groups Parfitt [4]
Summary
Sulphate is the most abundant form of sulfur found in soils under aerobic conditions and the main ionic species of this element that is absorbed by plants. It was noted that the significant decrease in the atmospheric emission of acidic reagents reached in some economically developed countries does not always result in an expected increase in the soil pH and a decrease in the sulfate concentration in the soil solution [3]. This is related to the complexity and inter relation of diverse reactions with the participation of sulfates in the “soil solid phase–soil solution” system, which is difficult to adequately describe by mathematical models. Equilibrium is established in this system under natural conditions; it is shifted under the effect of acid precipitation, and the new equilibrium takes different time periods in different soils to become established [13-22]
