Determination of surface acidity on the natural and synthetic montmorillonite clays has been carried out using the acid-base titration method to count the number of bound acid sites per gram of clay. The total acidity of natural and synthetic montmorillon... see more

The objective of this work was to evaluate the ability of CCC as an adsorbent material for the acidity removal of RFO, aiming at the application of the oil in biodiesel production. For that, a RCCD was used for FFA removal by applying the CCC and CAC for ... see more

Low soil fertility in Bangka becomes the main problem in permanent pattern of pepper cultivation. Utilization of micro and mesofauna plays a role in the decomposition of organic matter, improving soil structure, recycling of nutrients and reducing nutrien... see more

The aim of the study is to find iron availability and binding pattern by dietary fiber macromolecule on combination of acidity and length of boiling time, through Kads and Keff, boiling procees at the level of pH 4 and 7 with boiling time at 0 (raw), 5, 1... see more

In this study, the effect of calcination temperature and Si/Al mole ratio on acidity and physicochemical properties of silica SBA-15 were inves­tigated. Silica SBA-15 samples were calcined at 350, 450 and 550 °C, and then post-synthesis, the Al-grafting m... see more

Aluminium toxicity has been recognized as one of the most common causes of reduced grape yields in vineyard acid soils. The main aim of this study was to evaluate the effect of two liming materials, i.e. dolomitic lime and sugar foam, on a vineyard cultiv... see more

Natural zeolite modification with the addition of ammonium salt variations was conducted. The modification was conducted by demineralization method, dealumination and followed by activation of ammonium salt. The types of activators were ammonium chloride,... see more

The influence of cooling over the titratable acidity - DAr materialozes itself in all cases in a growth of medium values of the parameters, of values of ths growth are different: only 0,8 ºT at the HCA 8000 cooler, 1, 09 ºT at the HCA 5000 cooler and even... see more

Abstract Our study evaluated the acidity of broiler meat in accordance with some ante-slaughtering factors such as: duration of transport from farm to slaughterhouse, broilers’ density in transport shelves and ante-slaughtering rest time. To carry out t... see more
