TLDR
The results indicate that the adsorption process is favored at pH 9.5, which is close to the optimum conditions for the best adsorbent formation.Abstract:
Removal of nickel ions from industrial effluents has been studied using activated alumina prepared by the galvanic oxidation of aluminum metal at ambient temperature as the adsorbent. The effect of various factors, such as initial concentration of nickel, contact time, dose of adsorbent and pH of the solution has been investigated. Batch and column type of adsorption studies have been made. The results indicate that the adsorption process is favored at pH 9. The adsorption data were fitted with suitable adsorption isotherm. The optimum conditions for the best adsorption have been evaluated for the following factors: dosage, contact time, pH, initial concentration of nickel ions and temperature. The process of regeneration of the adsorbent has also been studied.read more

Functional analysis of AHK1/ATHK1 and cytokinin receptor histidine kinases in response to abscisic acid, drought, and salt stress in Arabidopsis

TL;DR: Gain- and loss-of-function studies in Arabidopsis indicated that AHK1 is a positive regulator of drought and salt stress responses and abscisic acid (ABA) signaling, and cytokinin clearly mediates stress responses because it was required for CRE1 to function as a negative regulator of osmotic stress.
