In this study, polyamine-polyurea polymer was synthesized using toluendiisocyanate and polyethyleneimine. It was then modified using pyromellitic dianhydride. The polymer so obtained (PMPPP) was used for the adsorption of ...

In this study, a polyamine-polyurea polymer modified with pyromellitic dianhydride was used for batch adsorption of Cu(II), Ni(II), and Pb(II) ions to examine the effects of parameters such as pH, contact time, amount of ...

This study investigates cadmium (Cd) accumulation in the plant leaves of juglans regia (walnut) and cydonia oblanga (quince) trees related to traffic emissions on the highway roadside. The plant leaf samples were collected ...

The present study reports a synthesis of novel polymeric sorbent of polyamine-polyurea polymer modified with 2,4-dihydroxybenzaldehyde (DMPPP) and analysing of its adsorption efficiency towards some metal ions including ...

In the present study, polyamine polyurea polymer was employed for adsorption of Cr(VI) ions from aqueous solution. Adsorption studies were carried out to examine the effects of parameters such as pH, contact time, initial ...

In this study, activated carbon (HHPAAC) was prepared from hazelnut husks using phosphoric acid activation and characterized by some physicochemical analyses. Surface area and zero point charge of pH (pH(PZC)) were found ...
