Given the potential of acid-activated clays in adsorptive and catalytic processes, several studies focusing on acid matrices have grown over years, making it possible to study vermiculite, a mineral composed type 2:1 unit cell with tetrahedral octahedral sheets. Therefore, this work aimed vermiculite treated acids for production matrices. In work, treatment natural vermiculite-hydrobiotite, nit...

Phenolic compounds are toxic and ominously present in industrial effluents, which can end up water bodies, causing potential damage to living organisms. This study employed the dried biomass of freshwater green microalgae Chlorella vulgaris remove phenol 2-chlorophenol from an aqueous environment. C. was grown under different phosphorus- (P) starved conditions, treated with sulfuric acid. It ob...

abstract effect of different concentrations of salicylic acid on postharvest life of kiwifruit (actinidia deliciosa) cultivar hayward at 0 ±.5 °c and 90-95% rh was studied. fruits were treated with salicylic acid (0, 1 and 2 mmol/l-1) and stored at 0±.5°c for 16 weeks. fruit quality attributes assessment including firmness, total acidity, soluble solid content, ascorbic acid, antioxidant activi...

in present research the effects of four levels (0, 0.5, 1, 2 mm) of each of salicylic acid and putrescine treatments on the quality improvement of granny smith apple fruit were studied. factorial experiment in randomized complete block with three replications on 16 trees, eighteen years in researcher station of agriculture university of tehran was designed. for this purpose the trees were spray...

nanosilver of nanometer-sized silver (ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. boric acid (h3bo3) is water soluble (ph=7). boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the acc synthase and acc oxidase delays senescence of flower. in this study of different concentrations of boric acid and nano-silver was eva...
