IIT Guwahati uses aloe vera to remove oil from water

Oct 27, 2018· We were able to use the aloe vera gel-coated membrane at least 25 times to separate oil from water, and the efficiency of separation remained above 97%, says Uttam Manna (centre)...

An Encapsulation

A metal-organic framework (MOF) material was integrated with surface superhydrophobicity, high surface areas, large and uniform pore sizes, and excellent stability This synthetic procedure was completed via an encapsulation-rearrangement strategy Benefiting from the superhydrophobicity, this MOF could be stable in humid environments and maintained its mesoporosity and surface areas for at ....

Recent advance of two

Oily water treatment has become an urgent task in our daily life because of the environmental and economic demands Traditionally, gravity separation, flotation and filtration are used to separate oil/water mixtures successfully, but these methods have some drawbacks, including energy waste, low efficiency and secondary environmental pollution...

A Novel PAN

water bodies, causing serious environmental problems [1,2] The oil contaminations can be broadly classified into free, dispersed, and emulsified oil, with the main difference being the size of oil droplets Among all, emulsions with a droplet size of less than 20 microns are the most stabilized and difficult to separate oil-water mixture [3,4]...

Magnetoactive Superhydrophobic Foams for Oil

Sep 01, 2012· A novel composite material for the efficient separation of oil from water is presented It is based on polyurethane (PU) foams modified with colloidal superparamagnetic iron oxide nanoparticles (NPs) in their whole volume and sub-micrometer polytetrafluoroethylene (PTFE) particles on their surface The hydrophobic and oleophobic original foam becomes water-repellent and oil-absorbing due to ....
