M. Mohammadi; A. Mohammadi Torkashvand; P. Biparva; M. Esfandiari

Volume 5, Issue 4 , Autumn 2019, , Pages 485-500


  Four diverse chlorides layered double hydroxides with diverse ratios, i.e. Mg-Al (3:1), Mg-Al (4:1), Zn-Al (4:1), and Zn-Al (3:1) LDHs, were prepared to evaluate their efficiency and selectivity towards nitrate removal from aquatic solutions. A batch experiment was done at the initial nitrate concentration ...  Read More

Volume 5, Issue 1 , Winter 2019, , Pages 61-70


  Congo red is a synthetic azo-dye dye with many industrial applications. The effluents containing azo dyes are causing several environmental hazards and thus should be treated prior to their discharge. The present work investigates the possible use of a novel microbial consortium from sheep compost for ...  Read More

3. A new kinetic model for biogas production from co-digestion by batch mode

D. Pham Van; M.G. Hoang; S.T. Pham Phu; T. Fujiwara

Volume 4, Issue 3 , Summer 2018, , Pages 251-262


  Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. ...  Read More

4. Comparative potential of black tea leaves waste to granular activated carbon in adsorption of endocrine disrupting compounds from aqueous solution

A.O. Ifelebuegu; J. E. Ukpebor; C. C. Obidiegwu; B. C. Kwofi

Volume 1, Issue 3 , Summer 2015, , Pages 205-214


  The adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol A on locally available black tea leaves waste and granular activated carbon were investigated. The results obtained indicated that the kinetics of ...  Read More

5. Equilibrium and kinetic study on chromium (VI) removal from simulated waste water using gooseberry seeds as a novel biosorbent

J. Aravind; G. Sudha;; P. Kanmani; A.J. Devisri; S. Dhivyalakshmi; M. Raghavprasad

Volume 1, Issue 3 , Summer 2015, , Pages 233-244


  Gooseberry seed (Phyllanthus acidus) was used as an adsorbent to determine its feasibility for the removal of Cr(VI). Various parameters such as pH, temperature, contact time, initial metal concentration and adsorbent dosage were investigated to determine the biosorption performance. Equilibrium was ...  Read More
