Freundlich Adsorption Isotherm

In order to improve the removal ability of hexavalent chromium on the synthetic zeolite, the synthetic zeolite was modified by FeSO4, which was used to removal hexavalent chromium in groundwater. The results showed that the concentration of Cr (VI) can be reduced from 5.0mg/l to 0.03 mg/l, which meets the requirements of groundwater standards (0.05mg/l) by using modified zeolite in a liquid-to-solid ratio of 20 ml/g, pH=3 for 120 minutes. The adsorption of Cr (VI) on the modified synthetic zeolite could be described by the Langmuir and Freundlich adsorption isotherm. It is showed that the synthetic zeolite modified by FeSO4 has good treatment effect and after treatment the pH of groundwater can reach around 6.8, which need no more pH adjustment.

Management Approaches

Several management approaches against red ant of potato Dorylus orientalis (Westwood) were studied at farmer’s field in Cachar district of Assam (India) during 2015-16 cropping season to find out the most effective man-agement technique. Combination of Malathion 5% dust @ 40 kg per hectare and Mustard Oil Cake (MOC) @ 150 kg per hectare reduced red ant damage significantly (p ≤ 0.05) followed by Dursben 20% EC @ 5 ml per litre and Car-bofuran 3G @ 25 kg per hectare. Malathion and MOC was applied at the time of first earthing up gave the lowest infestation of red ant (9.2%) and with (64.31%) infestation reduction over control closely followed by Dursban 20% EC (13.5%) and with (59.32%) infestation reduction over control. Highest infestation (47.6%) was recorded in the control untreated plot where; only chemical fertilizers were applied at recommended dose.
