Correlations between physico-chemical properties and nickel adsorption parameters in soils used in sanitary landfill liners

Correlation between soil physico-chemical properties and available micronutrients in salt affected soils

Twentyfour surface soil samples (0-30 cm) collected from salt affected area of Vasantdada Sugarcane Research and Development farm Manjari(Bkk.), Pune, Maharashtra (India) were studied for the Cu, Zn, Fe and Mn status in relation to important soil factors. All the soil samples had adequate amount of Cu, Zn, Fe and Mn. Iron and Maganese are significantly positively correlated with organic carbon,...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...

Distribution of zinc and copper chemical forms and their relationship with some physico-chemical properties and clay minerals in some calcareous soils

Determination and recognition of relative distribution of chemical forms of each element and their relationship with physical, chemical and soil clay minerals can help researchers to manage soil fertility better. This research attempted to recognize chemical fractions of zinc (Zn) and copper (Cu) in some surface and subsurface soil samples of Kohgiluyeh and Boyer-Ahmad province and their relati...

Physico-chemical properties of nettle seed oils grown in Iran

Identification of a Suitable Place for Sanitary Landfill in Ilam

Introduction: The location of sanitary landfills is one of the most important environmental issues in cities. If the design of landfills is not appropriate, it will threaten human health. This study aimed to detect a suitable location for a landfill in Ilam, Iran.   Materials & Methods: A questionnaire and consultation with experts were used to conduct the research. For this purpose, three ma...
