Calcium chloride Wikipedia

2 天前· Calcium chloride is an inorganic compound, a salt with the stone formula CaCl 2.It is a white coloured crystalline solid at room temperature, and it is highly soluble in water. It can be created by neutralising hydrochloric acid with calcium hydroxide.. Calcium chloride is commonly encountered as a hydrated solid with generic formula CaCl 2 (H 2 O) x, where x = 0, 1, 2, 4, and 6.

Magnesium incorporated bentonite clay for defluoridation

Low cost bentonite clay was chemically modified using magnesium chloride in order to enhance its fluoride removal capacity. The magnesium incorporated bentonite (MB) was characterized by using XRD and SEM techniques. Batch adsorption experiments were conducted to study and optimize various operational parameters such as adsorbent dose, contact time, pH, effect of co-ions and initial fluoride
