Deterrent B, a compound apparently involved in the resistance of Melilotus infesta to the sweetclover weevil Sitona cylindricollis, has been isolated from leaves by a combination of preparative paper chromatography, sublimation, and crystallization. The compound has been identified as ammonium nitrate. Isolated deterrent B and ammonium nitrate have identical feeding deterrent activities. Althou...

Lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. These are subsequently recovered from the resin by 0.5M ammonium citrate eluent at pH 2.0. Under optimized conditions, quantitative recovery ...

Anionic reactive dyes used to dye nylon suffer from failures due to the poor efficiency caused by low degree of exhaustion and fixation. From the previous work , the dyeing efficiency of Procion Rubine XL on modified nylon was particularly week and hence offers the widest scope for an in depth investigation in to variables that effect the dyeing process. The variables dyeing studies for this pr...

Abstract Aqueous ammonium‐ion (NH 4 + ) batteries (AAIB) are a recently emerging technology that utilize the abundant electrode resources and fast diffusion kinetics of NH to deliver an excellent rate performance at low cost. Although significant progress has been made on AAIBs, is still limited by various challenges. In this Minireview, most recent advances comprehensively summarized discussed...

Regeneration of sulfuric acid and ammonia from ammonium sulfate by bipolar membrane electrodialysis (BMED) coupling with stripping ammonia by air-blowing was studied. The result showed that it was feasible to regenerate sulfuric acid and ammonia from ammonium sulfate solution using this method. Empirical models to describe the ion and water transport behaviors through anion exchange membrane fo...
