ABSTRACT The present work was done in order to develop and find out suitable conversion methods for coconut husk wastes into value-added products. It is well-known that coconuts husk waste is hydrophobic therefore ethanol with different doses was used as a surfactant to enhance the removal efficiency. Trea...

ABSTRACT A novel method for the separation/analysis rhodamine B has been described. The ionic liquid (1-tetradecyl-3-methylimidazolium bromide)/anion surfactant (sodium dodecyl sulfate)/NaCl two-phase systems (ATPSs) is presented as a simple, rapid and effective sample pretreatment technique coupled with ultraviolet spectrometry for analysis rhodamine B in soft drink. The effects of parameters on the ATPSs extraction of rhodamine B such as amount of surfactant, ionic liquid and salt, pH, temperature, stabilization and centrif...

ABSTRACT The method of Ti/TiO 2 -NiO photoelectrode prepared by using sol-gel method continued by calcination process was introduced. The prepared TiO 2 -NiO film was observed with XRD and TEM. The anatase-rutile TiO 2 was mainly on the prepared TiO 2 -NiO composite surface electrode. In ...
