The adsorption process fitted the Langmuir isothermal models. The apparent maximum adsorption capacity was /g. The characteristics of palygorskite modified were acicular or fibrous, some other crystals gathering in it, more pores, very large specific surface area, it had the advantage to remove TPH from petroleum contaminated groundwater by absorption method.

Sokolova, 1971). . modification/high pressure homogenization integration process based on a lot of In this process, raw minerals were crushed and grinded as powder ...
Palygorskite and sepiolite are excellent absorbents and are essential for use as carriers for fertilizer, insecticides, and pesticides in agricultural applications when blended with bentontite, the material is a superior barrier clay for use in landfills and toxic waste repositories.
In the present paper, palygorskite, a natural magnesiumcontaining clay mineral, was investigated for catalytic pyrolysis of rape straw in situ and compared with the dolomite researched widely. The two types of natural minerals were characterized with XRD and BET.
Use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. The engineering controls also need to keep gas, vapor or dust concentrations below any lower explosive limits. Use explosionproof ventilation equipment.
