Volume 5, Special Issue , 2019, , Pages 12-21

http://dx.doi.org/10.22034/GJESM.2019.05.SI.02

Abstract
  Soil erosion is one of the vital factors contributing to the loss of fertility and environmental degradation. Generally accepted diagnostics of eroded soils is based on comparison of the sloping soils profile depth with the watershed soils. In this case, there is a separate problem of slope soils with ...  Read More

A.M. Hatami; M.R. Sabour; A. Amiri

Volume 4, Issue 1 , Winter 2018, , Pages 9-18

http://dx.doi.org/10.22034/gjesm.2018.04.01.002

Abstract
  Oil refining is an inevitable step in production of edible and industrial oil. Bleaching is the most important process among the refining processes. Bleaching adsorption is the most common method and clay is the most widely used adsorbent in this method. Disposal of bleaching clay, as a waste from re-refining ...  Read More

5. Reactive dye extraction utilizing regenerated bleaching earth

M. Shahi; M.R. Sabour; G.A. Dezvareh

Volume 3, Issue 3 , Summer 2017, , Pages 299-310

http://dx.doi.org/10.22034/gjesm.2017.03.03.007

Abstract
  Bentonite bleaching earth is utilized for purifying used motor oil through a recovery process in order to improve the quality and stability of the final product. Indeed, spent bleaching earth is generated due to adsorbing oil impurities. Polluted spent bleaching earth contains 20-40% (w/w) oil and is ...  Read More

http://dx.doi.org/10.22034/gjesm.2017.03.02.008

Abstract
  Fresh water source scarcity in arid and semiarid area is limitation factor for saline-sodic soil reclamation. The reusing of agricultural drainage and industrial wastewater are preferred strategies for combating with this concern. The objective of current study was evaluation in application of industrial ...  Read More

7. Responses of endogenous proline in rice seedlings under chromium exposure

X.Z. Yu; M.R. Lu

Volume 2, Issue 4 , Autumn 2016, , Pages 319-326

http://dx.doi.org/10.22034/gjesm.2016.02.04.001

Abstract
  Hydroponic experiments were performed to exam the dynamic change of endogenous proline in rice seedlings exposed to potassium chromate chromium (VI) or chromium nitrate chromium (III). Although accumulation of both chromium species in rice seedlings was obvious, more chromium was detected in plant tissues ...  Read More
