The work is dedicated to study the production of microcrystalline cellulose (MCC) from sunflower seed husks (SFH) by oxidation in an organic solvent, dependence its hydromodule, yield and quality index MCC on type. According morphological characteristics SFH with different fat content, effective hydromodulus obtained low-fat 1:12 g/mL a 50.69%, while for high-fat SFH:PAA 1:14 g/mL, it was deter...

Technology intervention is a key success to restore properties and productivities of a highly weathered soil (Oxisols). The main challenge is to find materials with the ability to generate soil negative charge, release various nutrients and suppress toxic elements. The objective of this study was to increase negative charge and nutrient content, and suppress Al and Mn toxicities of an Oxisol us...

The influence of crop residue amendments on the chemical properties of an acid soil and rice yields was investigated at Abakaliki for two cropping growing seasons (2006 and 2007). The residue treatments were rice straw, burnt rice husk and legume residue, while the rice cultivars were ITA 315, Ex-China and ITA 257. The design of the experiment was a 3 x 4 factorial in a Randomize Complete Block...

Roxb., locally known as “Ketepeng China” from the family of Fabaceae, is a shrub or small tree that used an ornamental flowering and for medicinal purposes in tropical subtropical countries. Various parts S. plant (leaves, flowers, roots, stem) are traditional medicines to treat typhoid, diabetes, malaria, asthma, ringworms, scabies, eczema. The present study was desig...

Surfactants are one of the major components (10- 18%) of detergents and household cleaning products and are used in high volumes in developed countries. In the present research work, the ability of rice husk as a low cost adsorbent for anionic and nonionic surfactants in wastewater has been studied. The maximum removal efficiency for anionic surfactants was 97%, in an aqueous solu...
