The materials with high adsorption ability play a key role to remove industrial pollutants from water in the use of adsorption method.
In general, materials with many ion exchange sites and high surface area possess high removal capacities.
Mesoporous materials with large pore sizes and high surface areas are also promising adsorbents for various pollutants in water.

Effect of Ce(SO4)2 Additive on Coating Formed by Micro-arc Oxidation Process on Casting Aluminum-copper alloy Defeng Wu a, Xiaoyan Zhang*, b, Yuanyuan Lei c, Xiaosong Zhou d College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China.
The MAO coatings surface is constituted by many tiny, volcanic cone-like materials, and there are many different sizes of holes on them.
With the increasing concentration of Ce(SO4)2 in the electrolyte, the volcanic cone-like materials on the ceramic coating surface accumulate obviously, this shows that Ce(SO4)2 contributes to MAO reaction.

The manufacturing scheduling program has to optimize the structure of the production , lower the rejectscheaply and enhance the durability and after severce in order to make the product reliable. 2) Product cost: including the utilization ratio of equipment, cost of the raw materials and wastes discharge.
The manufacturing scheduling program should apply new and high technogy to enhance utilization ratio of equipment, save the product raw materials and reduce the wastes discharge. 3) Product safety: including equipment loading, equipment block and shortage of material.
By the figure, we can see that the weights of the factors of the manufacturing scheduling program have this relation: equipment loading> shortage of the material>equipment block>customer satisfaction>equipment efficiency>product quality>cost of raw material>wastage discharge.
