background: the efficacy of nh4cl-induced activated carbon (nac) was examined in order to adsorb rr198, an azo reactive model dye, from an aqueous solution. methods: the effects of ph (3 to 10), adsorbent dose (0.1 to 1.2 g/l), dye concentration and contact time on the adsorption efficiency were investigated. results: the results showed that the removal of dye was highest at a solution ph of 7 ...

Background & Aims of the Study: Natural organic matters (NOMs) are a mixture of chemically complex polyelectrolytes produced mainly from the decomposition of plant and animal residues that are present in all surface and groundwater resources. This paper evaluates the aqueous NOMs adsorption efficiency on walnut shell modified with Zinc Oxide (ZnO). Materials & Methods: This stud...

In this study, organic amines were used to modify zeolite NaA and analcime synthesized using fly ash iron tailing slag as raw materials, respectively, the adsorption properties of modified zeolites toward CO2 determined. We found that when tetraethylenepentamine (TEPA) was used, had highest nitrogen content. The capacity for 4.02 mmol/g 1.16 temperature 70 °C flow rate 50 mL/min. According isot...

The probiotic juice is one of the newest innovation opportunities in various kinds of healthy drinkꞌs business. The aim of this study was to investigate effect of banana pureeꞌs on survival of Lactobacillus casei and physicochemical and sensory properties of cocktail juice containing apples and bananas juice during storage. The amounts of banana puree were added in 3 levels (7% and 15%) to appl...

The effects of pineapple juice (PJ), pineapple shell extract (PSE) and rice bran extract (RBE) on browning in the banana slices and puree compared with citric acid solution (pH 3.8) (PH) and distilled water (DW) were investigated by measuring the color changes of the banana slices and puree. RBE treated banana slices had lower browning value than those treated with PJ, PSE, PH and DW after stor...

The adsorption of polyester onto organically modified silicas (ormosils) and (commercial) fumed silica has been compared utilising ToF-SIMS. The thermodynamics of each system was examined by constructing adsorption isotherm plots which indicated that the adsorption of polyester onto one of the modified silicas used may be a two stage process. Adsorption onto the fumed silica is in accord with t...

Cavendish (Musa paradisiaca L, cv cavendshii) and Dream (Musa acuminata colla. AAA, cv ‘Berangan’) banana flours were prepared from ripe fruits collected from eleven markets located in Penang, Malaysia. The mineral composition (Na, K, Ca, Mg, Cu, Fe, Mn, Zn) of the flour were analyzed by atomic absorption spectrophotometer and the data obtained were analyzed using logistic regression model. Rip...

The methylene blue (MB) adsorption from the aqueous solution on activated charcoal soapnut shell & pineapple waste were studied in batch mode. influence of a major parameter determining efficiency process, such as initial concentration, adsorbent dose and contact time removal was studied. Experimental studies have shown that capacity increases with increase decreases concentration. equilibr...
