Correlation of microstructure and flexural strength of fly ash geopolymer of varying molarities
(IOP Publishing Ltd, 2019-08)
The present work studies and compares the flexural properties of fly ash geopolymer with varying molarity of sodium hydroxide (NaOH). Different molarities of NaOH solution (6M, 8M, 10M, 12M and 14M) are used to prepare the ...
Preparation of heat treated Titanium Dioxide (TiO₂ ) nanoparticles for water purification
(IOP Publishing Ltd, 2018-06)
Photocatalysis using the semiconductor titanium dioxide (TiO₂) has proven to be a successful technology for waste water purification. The photocatalytic treatment is an alternative method for the removal of soluble organic ...
Degradation of organic matter from stabilized leachate by using zinc sulphate as coagulant agent
(IOP Publishing Ltd, 2018-06)
Stabilized landfill leachate often contains higher organic fractions than the young one. The organics require several sequential treatments to render the leachate parameters concentrations to permissible discharge limits ...
Characteristics of thermoplastic potato starch/bentonite nanocomposite film
(IOP Publishing Ltd, 2018-06)
