Oil spill formed in aquatic environments such as oceans, seas or even rivers are one of the environmental hazards. Oil pollution from port activities, sea shipment, oil tanker accidents, oil well drilling and war is a serious threat to coastal waters and ports, could cause hazards such as port fire, coastal and aquatic pollution, and marine ecosystem disruption. making port environments disgusting for tourism activities.

Clinoptilolite zeolite is a natural mineral that due to its properties such as porous structure and high adsorption, as well as mechanical stability, lightness, reasonable price, and environmental friendliness and non-toxicity can be very useful oil spill clean up in aquatic environment.

GMSN-Z85 is a type of clinoptilolite composite that has higher adsorption and lower specific gravity due to structural changes and modifications on natural clinoptilolite. This composite is a high-strength hydrocarbon adsorbent that has the ability to absorb oil slicks floating on the water surface.
