Introduction: Elemental sulfur is byproduct of natural gas refining which during this process, HS is removed from sour gas and after changes to solid sulfur, it is stored in large block forms. Continuous precipitation of sulfur and its oxidation causes soil acidification and as a result, nutrient cations such as Ca+, Mg+, Na+ and K+ will leach from the soil profile. Also, sulfate accumulation led to soil acidification and accelerates the silicates weathering in upper layer of the soil profile. Accumulation of water soluble sulfate in the soil and increase the nutrient cations leaching from the soil depend on sulfate resistance rate. Also, addition of sulfur to the soil for a long time can cause calcium sulfate formation that will cause problems such as increase in soil salinity. Shahid Hashemi Nezhad gas refinery is located about km south of Sarakhs city and about km east north of Mashhad. In addition to exploiting, refining and producing × m.day- natural gas, recovered sulfur with %/ purity and tons per day production capacity is one of the byproducts of this gas complex.

This widely used substance has various states such as gas, liquid and solid states, about which there is still no complete information about how they are formed from one form to another and the relationship between them.This material has many metallic properties but not even a single metal atom in it and this is surprising and this element has electrical and optical properties. It may not seem obvious, but sulfur plays an important role in the daily lives of all of us.

Sulfur is one of those elements that has a clear past. Its origin and use date back to centuries ago, the time when the Greeks used this substance to disinfect their homes and the properties from burning it. They took.Mankind has mentioned the existence in Sicily and Italy for centuries. Its common name in the past was brimstone and it means a burning stone. In the Bible, sulfur is given the same name.

It is used to produce sulfuric acid, which is a suitable substance in fertilizers.Direct use in agriculture: This substance is used directly to strengthen plants and their genetic modification. asphalt production: This type of asphalt is made by combining this material with bitumen and stone and is used in road corners, end of roads and parking places to prevent asphalt removal. Sulfur has been known and used for more than a thousand years.consumption in industries is very diverse, so that in the past and usage was often measured as an indicator to determine industrial activities in the country.

ترکیبات گوگرد بسیار سمی است.، برای مثال مقدار کمی سولفید هیدروژن می‌تواند متابولیسم بدن را دگرگون کند اما مقادیر بیشتر آن می‌تواند به سرعت باعث مرگ از راه فلج تنفسی شود. سولفید هیدروژن با سرعت حس بویایی را از بین می‌برد. دی‌اکسید گوگرد آلوده‌کننده مهم جوی می‌باشد. این عنصر برای است.فاده‌های صنعتی مانند تولید اسید سولفوریک (HSO) برای باتری‌ها تولید باروت و حرارت دادن لاستیک تولید می‌شود. گوگرد در فرآیند تولید کودهای فسفاتی به عنوان ماده ضد قارچ عمل می‌کند. سولفات‌ها در کاغذهای شستشو و خشکبار نیز کاربرد دارند. همچنین این ماده در ساخت کبریت و در آتش‌بازی نیز به‌کار گرفته می‌شود. تیوسولفات آمونیوم یا سدیم به عنوان عامل ثابت کننده در عکاسی کاربرد دارد. سولفات منیزیم می‌تواند به عنوان ماده ضد خشکی و ملین که یک مکمل منیزیم گیاهی است. به کار گرفته شود.
