In this study, we investigated the effects of organic waste and moisture superabsorbent on the amount of available water and delay in moisture equivalent of permanent wilting point (PWP) in soil. In the first phase (soil incubation phase), 12 treatments were studied in a completely randomized design at the Soil Science Laboratory of Science and Research Branch, Tehran. The treatments c...

This work proposes a novel approach for colorimetric assays using ubiquitous and inexpensive water beads (WBs) made of superabsorbent polymer (sodium polyacrylate). The high-water absorption capacity by the WBs was exploited preconcentration iron ions from samples tap, well, lake waters. Moreover, also worked as substrate detection classical reaction formation Fe(II)-phenanthroline complex. Dig...

Abstract Smart hydrogels, or stimuli-responsive can and should play an important role as excellent drug carriers. These three-dimensional structure materials are composed of crosslinked hydrophilic polymer chains that able to dramatically change their volume other properties in response environmental stimuli, such pH, temperature solvent changes. The main goal individual research projects was t...

a hydrophilic macromolecular network is prepared by performing graft copolymerization of poly (sodium acrylate) chains onto salep and silica gel. the reaction parameters affecting the water absorbency of the superabsorbent composite were optimized using taguchi method. ft-ir spectroscopy and thermo gravimetric analysis (tga) were used for confirming the structure of the final product and morpho...

to investigate the effect of droughtstress on chlorophyll content, enzymatic responses and some growth characteristics of acacia victoriae seedlings and the effect of super-absorbent polymers (sap) in reducing drought stress, a split plot experiment based on the completely randomized design was conducted. the treatments included four levels of drought stress (15, 30, 60 and 100% of field capaci...

This study investigated the effects of a crystalline admixture (CA) and superabsorbent polymer (SAP) on self-healing mechanical properties basalt fibre mortars. Uniaxial compression experiments were conducted mortar specimens to investigate two admixtures different ratios strength repair ability at maintenance ages after pre-cracking, microscopic observations cracks their healing products using...
