Approximately 857,000 tonnes of tea is produced in India per year, which is 27.4% of total world production. After processing, tea factory waste is about 190,400 tonnes. Batch adsorption studies have been carried out for evaluating the suitability of tea factory waste as a low-cost adsorbent for the

Equilibrium adsorption/desorption isotherms of organic vapor (MeOH, EtOH, i-PrOH, and Me2CO) at 298 K were measured on two hydrophobic porous coordination polymers, [Zn2(1,4-bdc)2(dabco)]n (1, 1,4-bdc ¼ 1,4-benzenedicarboxylate, dabco ¼ 1,4-diazabicyclo[2.2.2]octane) and [Zn2(1,4-ndc)2(dabco)]n (2,

This paper considers the importance of automobiles as a continuing source of persistent pollutants in the environment, using the UK as a case study. The mass of lead, copper, zinc and polycyclic aromatic hydrocarbons (PAHs) being released by automobiles in the UK is estimated. It is shown that as ot

The transport of zinc complexes ions through an anion exchange membrane was evaluated by the treatment of solutions with and without cyanide. The ionic transport was analyzed as a function of the applied current density and of the cyanide and hydroxyl concentration. Experimental results showed that

In this study, a microbial surfactant, rhamnolipid, was investigated for its potential to enhance recovery of Zn(II) from Na-feldspar as soil component. The effects of rhamnolipid concentration, pH, and initial Zn(II) ion concentration on the removal of Zn(II) ions from Na-feldspar by rhamnolipid bi

Scaling, often due to the precipitation of calcium carbonate, is a current problem in economical and technical life. To study this phenomenon, some experimental procedures have been developed. They are based for example on electrochemical precipitation, use of nanofiltration and rapid controlled pre

There is a stringent need for the control of toxic metals produced during various production processes and released into the aqueous environment in order to avoid damage relevant to soil or groundwater contamination. Among the available treatment technologies, sorption has been considered of particu
