In this paper, the effect of chitosan molecular weight on the characteristics (size, encapsulation efficiency, zeta potential, surface morphology and release rate) of vitamin C encapsulated tripolyphosphate cross-linked chitosan (TPP-chitosan) microspheres. The molecular weight of chitosan had a noticeable influence on the size, encapsulation efficiency, zeta potential, surface morphology and c...

To evaluate the efficacy of biochelators for phytoremediation cadmium (Cd), effects (humic acid, HA; polyaspartic PASP; rhamnolipid, RLs) and synthetic chelator (sodium tripolyphosphate, STPP) on growth, accumulation, antioxidant index Cd were investigated in Iris sibirica L. The results indicated that addition HA increased dry weight leaves stems, PASP, RLs, STPP growth but inhibited stems. de...

This research aims to analyze the impact of sodium tripolyphosphate (STPP) as a rheological modifier concentrated kaolin slurries in seawater at pH 8, which is characteristic copper sulfide processing operations. The dispersion phenomenon was analyzed through chord length measurements using focused beam reflectance measurement (FBRM) technique, complementing size distributions unweighted and sq...

In order to solve the problem of frequent drug dosing and increase its effectiveness, theophylline (THP) was deposited on chitosan nanoparticles (CSNPs). THP-CSNPs nanocomposites with composition 50, 75, 100 or 150 mg (CS) 25, 200 tripolyphosphate (TPP) at pH 4.0, 5.0, 6.0 6.5 were prepared, a constant weight THP mg. The characterized by X-ray diffraction (PXRD), field emission scanning electro...

Slip casting is a ceramic processing technique which can be used to produce complex-shape object. In the present work, slip was applied 70 mm × 10 15 green samples from recycled soda-lime glass. The with 60% solid loading prepared 100 g of cullet, 1 sodium silicate as binder, 50 ml DI water, and 16.7 deflocculant. deflocculant for 0.1 wt% tripolyphosphate solution. After casting, were dried at ...

in this work, the effect of presence of the sodium tripolyphosphate (stpp), as an inorganic salt, on improving the performance of polyamide (pa) thin layer membranes has been studied. characterization analyses confirmed the presence of the salt on the whole surface structure of the thin layer. different salt loadings resulted in different fluxes and cu (ii) rejections. the thin layer containing...
