Oolites, Pisolites and Laterites Formation and Composition

Oolites, Pisolites and Laterites Formation and Composition

Oolites Composition: Oolite is a sedimentary rock made up of ooids (ooliths) that are cemented together. Most oolites are limestones — ooids are made of calcium carbonate (minerals aragonite or calcite). Description: Ooids are spheroidal grains with a nucleus and mineral cortex accreted around it which increases in sphericity with distance from the nucleus. …

Determine the Amount of Phosphate in the Laundry Effluent

Determine the amount of Phosphate in the Laundry Effluent

Introduction:  Phosphate salts are retrieved from naturally occurring minerals, which are mined, refined, and purified for use in many applications. Mostly Phosphate is used in agriculture as a fertilizer. Sources of Phosphate: Natural: Weathering of Phosphate-containing rocks is the cause of phosphate entrance in nearby rivers and streams (EEA, 2005). Anthropogenic: …

Determine the Amount of Sulfate by Turbidimetric Method

Determine the amount of Sulfate by Turbidimetric Method

To Determine the Amount of Sulfate by Turbidimetric Method Introduction: Sulfates occur naturally in the form of minerals, like barite (BaSO4) and gypsum (CaSO4·2H2O). Sulfate also occurs naturally in drinking water. Sulfates are used in the production of fertilizers, chemicals, dyes, glass, paper, soaps, textiles, fungicides, insecticides, astringents and emetics. …
