boron (b) is an important plant essential micronutrient whose availability is influenced by many soil factors. adsorption–desorption processes play a major role in governing the solubility of boron in soil solution and, consequently, its availability to growing plants. to assess the effect of sodium adsorption ratio (sar) on availability of b, adsorption of b was investigated in a sampled calca...

This study assesses the adsorption performance of Java plum leaves and guava fruits based adsorbents as natural products widely available in Aceh, Indonesia. These renewable adsorbents were employed to remove free fatty acids (FFAs) that cause the rancid odor in coconut oil. The adsorption tests were carried out at three different doses (50, 75, 100 g) and seven agitating periods (1, 2, 3, 4, 5...

This work seeks to debunk the claim that Elovich isotherm is vastly inferior Langmuir or Freundlich in correlation of adsorption equilibrium data. mistaken finding, reported many published articles, a result comparing linearized versions three isotherms, which are based on different sets transformed When discrimination performed basis untransformed data (the conventional adsorbed phase concentr...

The biofiltration technique is of great importance for the removal heavy metals. In present work, a laboratory-scale biofilter was modeled using rice husk as filter material. Wolborska model used to know dimensions necessary function. Langmuir and Freundlich isotherms were performed quantify adsorption process, showing that are ones highest correlation coefficient best represent process Cd (II)...

in this study, removal of methylene blue (mb) and maxilon blue sl 200% (mb sl) dyes from aqueous solutions by using raw clay (rc) of nevsehir (turkey) vicinity and ultrasonic-acid modified clay (mc) was investigated. adsorption was carried out with 500 mg/l mb and 50 mg/l for mb sl in terms of different adsorbent dosages, contact time, solution ph, temperature and stirring speed. the fitting of...

Abstract Adsorption is an important phenomenon widely used for the removal of contaminants. Several drinking water contaminants such as arsenic and fluoride, vanadium chromium, nickel, cadmium cobalt are found to coexist in nature multi-component mixtures water. Hence, modeling adsorption isotherms designing treatment systems has gained importance recently. However, review studies competitive l...

background and purpose: phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. in this study, an activated carbon of miswak’s root (mr) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. materials and methods: adsorption experiments were then conduct...
