Activated carbon prepared from coir pith (ZnCPC) using ZnCl2 was investigated to find the feasibility of its application for removal of 2,4–dichlorophenol (2,4-DCP) in aqueous solution through adsorption process. Batch mode kinetics and isotherm studies were carried out to evaluate the effects of contact time, initial concentration, adsorbent dose, pH, and temperature. Lagergren, Second order, ...

Carbon slurry, dried in open air, has been used as an adsorbent material for the removal of nickel(II) from aqueous solutions at different experimental conditions in batch adsorption technique. The time required to attain equilibrium was found to be 50 minutes. The effects of initial concentration of Ni(II), particle size of adsorbent, adsorbent dose, temperature and pH on removal of nickel(II)...

Amine-containing adsorbents have been extensively investigated for post-combustion carbon dioxide capture due to their ability to chemisorb low-concentration carbon dioxide from a wet flue gas. However, earlier studies have focused primarily on the carbon dioxide uptake of adsorbents, and have not demonstrated effective adsorbent regeneration and long-term stability under such conditions. Here,...

Acacia polycantha frass (APF) generated by boring activity of Ambrosia beetles was investigated using a batch technique for its potential to adsorb Cr(III) ions from aqueous solution. Studies were carried out to determine the effect of pH, adsorbent dose, and KBr concentration on the sorption behavior Cr(III) on the adsorbent. The adsorption process was found to be highly dependent on solution ...

Nickel ferrite-polyaniline nanocomposite has been prepared and characterized using different techniques. The prepared nanocomposite is used as an adsorbent for the removal of arsenic from aqueous solution of sodium arsenite. The effect of temperature on the equilibrium adsorption of As(III) from aqueous solution on nanocomposite has been investigated. Effect of pH (2-12), contact time (0-70 min...

−Microsilica, one kind of industrial solid waste material, was utilized firstly to prepare a carbon-microsilica composite adsorbent (CMS). The prepared adsorbent was characterized with XPS, SEM and Gas sorption experiments. The results indicated the SO 3 H groups, which are very effective in capturing cationic organic dye, were introduced onto the surface of CMS; the Brunauer-Emmett-Teller (BET...

Olive oil is the most important commodities produced in the Mediterranean region. Due to its significant economical importance, the usage of pesticides in its production is systematic, by using a wide range of plant protection products with a variety of modes of action. As a consequence, monitoring of their residue levels in these products is a necessity. In the present study a reversed-phase h...

Many non-conventional adsorbent have been studied as economic alternative to commercial activated carbon and mostly agricultural waste have been introduced such as rubber leaf powder and hazelnut shell. Microwave Incinerated Rice Husk Ash (MIRHA), produced from the rice husk is one of the low-cost materials that were used as adsorbent of heavy metal. The aim of this research was to study the fe...

The research of the present work was to investigate the removal of Rhodamine B dyes from aqueous solution by using Activated Acacia Nilotica Shell Carbon (ANSC). Generally, dyes are organic compounds used as colouring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the indus...

Mycotoxins are secondary toxic metabolites that are produced by fungi representing threats to human and animal health. The objective of this study was to evaluate the adsorption capacity of Chitosan (CHI), and three cellulosic polymers (HPMC, CMC, and MCC), on six mycotoxins (AFB1; FUB1; OTA; T-2; DON; and, ZEA) using an in vitro digestive model for poultry. The adsorbent capacity of the materi...
