All-solid-state sensors with polyvinyl chloride (PVC)-based membranes using off-the-shelf N-hydroxysuccinimide (NHS) and succinimide (Succ) ionophores were prepared using DOP (dioctyl phthalate) and NPOE (ortho-nitrophenyloctyl ether) as plasticizers. Good responses were obtained when NHS was used. The potentiometric response of the proposed electrode is independent of pH over the range 2-6. Th...

A simple, highly sensitive, accurate and selective method for determination of trace amounts of Ni2+ in water samples. In this paper, Dioctylphthalate (DOP) was used to encapsulate nano-Fe3O4 and produce a nano-Fe3O4-DOP sorbent based new sorbent was prepared. This was treated with ethylenediamine (ED) in another solvent-free procedure for the formation of a novel nano-Fe3O4-DOP-ED. Flame atomi...

Abstract A polyester plasticizer (RSOP) for polyvinyl chloride based on rubber seed oil (RSO) was synthesized. Firstly, RSO monoglyceride were synthesized by the transesterification of with glycerol at 220–240 °C. Secondly, RSOP from and adipic acid esterification. The characterized GPC, FT-IR, 1 H NMR DSC. Plasticized (PVC) materials dioctyl phthalate (DOP) in varying ratios prepared via therm...

The aim of this study was to improve the adhesion performance of plasticized polyvinyl chloride (PVC) coatings on steel substrates by using nanoparticles. For this purpose, the PVC plastisol with different concentration of nano-silica was prepared and applied to bond steel joints. The adhesive strength of the joints was determined by single-lap shear test. Moreover, mechanical properties and mi...

In this study, the response surface methodology (RSM) based on the central composite design (CCD) was used to optimize the preparation condition of polypropylene-grafted maleic anhydride (PP-g-MA) microporous membrane by thermally-induced phase separation (TIPS) method. A mixture of dibutyl phthalate (DBP) and dioctyl phthalate (DOP) was used as diluent. The effect of polymer composition and qu...

Polyvinyl chloride (PVC) is made by polymerizing vinyl chloride monomer and is a plastic that softens on heating. The addition of a small amount (<5%) of plasticizer produces a hard PVC, whereas the addition of 30 to 50% plasticizer results in a soft PVC. Soft PVC is used to make several products, including chemical shoes, cables, gloves, hoses, and film. The principal component of PVC hose is ...

Primary organic aerosol (POA) and associated vapors can play an important role in determining the formation and properties of secondary organic aerosol (SOA). If SOA and POA are miscible, POA will significantly enhance SOA formation and some POA vapor will incorporate into SOA particles. When the two are not miscible, condensation of SOA on POA particles forms particles with complex morphology....
