Aluminum foil of milk packaging waste has a high aluminum content, so it can be used in the synthesis of coagulants Polyaluminum Chloride (PAC). The content of aluminum in the waste was extracted using HCl 15% for 150 ...

The adsorption ability of biocharcoal of Terminalia catappa leaves waste (BLDK-30; BLDK-60 and BLDK-120) has been studied using cation of Pb(II) in aqueous solution. The adsorption experiments were observed at each contact ...

Cengar clay has been used as a basic material for getting a liquid coagulant. Based on the content of Al and Fe which were given, three types of liquid coagulants were selected to use in coagulation process for decreasing ...

Salted fish scale has potential as an adsorbent for Pb metal removal from aqueous solutions under different experimental conditions. This study was designed to evaluate the effect of physical pretreatments and particle ...

Sulfuric acid activated Cengar clay was a side product of liquid coagulant. It was obtained by calcination of the Cengar clay at 500 oC for 3 hours and then extracted with sulfuric acid with varying moles (0,2 ; 0,4 and ...

Terminalia catappa leaves waste is a biomass waste that can found around at University of Riau area. It was used as a source of adsorbent. After carbonization at temperature 300 °C at time of 1 hour, biocharcoal of Terminalia ...

Nilon 6,6 -kaolin hybrid membrane is a combination of polymer (nylon 6,6) and inorganic compound (kaolin clay) prepared by phase inversion through immersion processes. This research has been done to determine the ...

Sulfuric acid activated clay is a byproduct of the synthesis of liquid coagulant. It has been used as an adsorbent for the adsorption of Fe (III) of Siak Riverwater. The clays were washed with aquadest until pH of the ...

This study focused on the use of Maredan clays as a catalyst in the esterification reaction. Maredan clays have been activated by chemical and physical modification, with variation of sulfuric acid concentration (0,1; 0,2 ...

Clay is one of the natural wealth that has been used as a liquid coagulant in water treatment. Natural clay can be used as a liquid coagulant caused the content of its aluminum and iron able to bind colloidal particles, ...
