Jan 01, 1996· The approximate sizes of limestone were 0.65 mm (0.59-0.71 mm) and 4 mm (3.8-4.5 mm) in diameter. The results indicated that the adsorption efficiency of the four metals decreased as the limestone size increased. This can be explained as the contact areas of metals and sorbent decrease as the sorbent becomes larger.

Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...
