    • Adsorption studies of heavy metal solutions using corn cobs adsorbents 

      Lim, Hooi Peng (Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2012-05)
      In this study, corn cobs were utilized as an adsorbent to remove heavy metals (Cu and Zn) from aqueous solution. The influences of initial Cu (II) and Zn (II) ion concentration (25 - 200 ppm) with contact time, temperature ...

    • Decolorization of azo dye by ozonation 

      Suhaida, Mohamed Arshad (Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2010-02)
      Decolourization and Chemical Oxygen Demand (COD) removal of azo dye solution in different ozonation time and biodegradation processes were evaluated to apply for wastewater treatment containing azo dye. Reactive Red 120, ...

    • Preparation, characterization and adsorption performances prepared from corn cob for removal of dye solutions 

      Sukanya, Ramaiah (Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2012-05)
      The objective of this study was to investigate the removal of Methylene Blue (MB) and Methyl Orange (MO) dyes from synthetic wastewater by the adsorption on treated and untreated corn cob adsorbents. Surface morphology was ...

    • Removal dye by adsorption onto pineapple peel powder 

      Teong, Hui Yin (Universiti Malaysia Perlis (UniMAP)School of Environmental Engineeering, 2011-05)
      The adsorption behavior of methylene blue on pineapple peel powder was studied on batch modes of operation. The operation parameters investigated including initial dye concentration (60-100mg/L), contact time, pH of solution ...

    • Removal of dyes from aqueous solution by chitosan in prawn shell: Adsorption equilibrium and kinetics 

      Masita, Che Omar (Universiti Malaysia Perlis (UniMAP)School of Environmental Engineering, 2011-05)
      Adsorption of brilliant dye from aqueous solution onto cross-linked chitosan composite beads was investigated in a batch system. Kinetic and isotherm studies were carried out by considering the effects of various parameters, ...
