Diatomite or diatomaceous earth (DE) is one of the materials which can be used as an adsorbent to treat waste water polluted with heavy metal ions.
Introduction Diatomaceous earth (DE) is used in many industrial fields: wastewater treatment, filtering, petroleum processing, cleaning product manufacture, manufacture of fire or heat resistant materials and additives for building materials, etc. [1-9].
Materials and Methods Raw DE from Lam Dong province was ground in ceramic ball mill for 30 min, demagnetized to remove iron, and passed through a 90 µm sieve.
The experiments were conducted at Materials Laboratory, Ho Chi Minh City University of Food Industry.

Cu(In,Ga)Se2 is a very important type of absorber layer material for high efficiency solar cells in material engineering.
In all the deposition method, such as co-evaporation, selenization, co-sputtering, electro chemical deposition and screen printing method, co-evaporation and selenization method can get the better quality of CIGS thin film among them, but when the CIGS film growth temperature is blow 400 ℃, the three-stage is inefficient for solar cells[8].RF magnetron sputtering is a commonly used method for the preparation of thin film materials, it is simple and easy to manipulate.
