Methyldopa, an antihypertensive, is a very close analogue of DOPA. Drug interaction accompanied by degradation in a banana juice mixture was reported for DOPA. However, the effect of banana on methyldopa has not been reported. Therefore, we have investigated the impact of banana juice on methyldopa. The drug and supernatant of banana pulp were mixed, and the mixture was observed for changes in ...

One of the most advantageous methods for lowering water hardness is use low-cost adsorbents. In this research, effectiveness natural zeolite (clinoptilolite type), activated carbon, and alumina was evaluated. These adsorbents were sequentially modified by NaCl, HCl, NaCl-HCL to improve their ability adsorb. The contact time amount adsorbent used in adsorption process investigated experimentally...

berangan banana were treated with hot water at 50 ºc for 0 (control), 10, and 20 min and then kept at room temperature (25±2 ºc), 75-80% rh to observe the ripening progress. firmness and activity of cell wall degradation enzymes such as polygalacturonase (pg), pectin methylesterase (pme), and pectate lyase (pl) were determined for treated and untreated banana. the microstructure of banana peel ...

Raw bentonite (RB), a known low-cost versatile clay was used as an adsorbent. RB was treated thermally and chemically to increase its adsorption capacity. For thermal treatment (TTB), the bentonite was heated at 400 °C for 60 min, and for the chemical modification, its surface was treated by cetyltrimethylammonium bromide (CTAB) to prepare organo-modified bentonite (CTAB-B). The removal of Cong...

Adsorption of cationic dye crystal violet (CV) onto a modified walnut shell (WS) adsorbent was investigated. Combined treatment WS using urea and sodium dodecylsulfate (SDS) carried out. Surface modification adsorbents confirmed by FTIR analysis, pHpzc measurements, elemental SEM-EDX analysis. In order to optimize the adsorption conditions, effect solution pH, dose CV concentration studied mean...

the removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. the results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. the results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution within 40...

background & aims of the study: p-chloronitrobenzene is a benzoic compound that widely used in many chemical industrials. p-chloronitrobenzene may be absorbed through the skin and is suspected to causing cancer. so, developing an easy method to remove of it from the environment is necessary. equilibrium isotherms and adsorption kinetics of p-chloronitrobenzene onto modified silk waste were stud...

Banana, an important component in the diet of the global population, is one of the most consumed fruits in the world. This fruit is also very favorable to industry processes (e.g., fermented beverages) due to its rich content on soluble solids and minerals, with low acidity. The main objective of this work was to evaluate the influence of factors such as banana weight and extraction time during...
