in the present work, the znfe2o4 nanoparticle has been successfully synthesized. the obtained sample was characterized by x-ray diffraction (xrd), emission scanning electron microscopy (fe-sem) and its optical property was examined by uv-vis spectrophotometer. fe-sem revealed that the particle size of the znfe2o4 of about 47 nm was synthesized. the photocatalytic performance under uv-vis and vi...

INTRODUCTION In spite of being the fastest acting drug available for the control of an acute gout attack, colchicine is generally considered a last alternative in gout therapy. This is mainly due to the severe adverse effects associated with its administration through the enteral and parenteral routes, as well as its high risk/benefit ratio. The preparation of dosage forms of colchicine that ca...

Sun protection products, including sunscreen lotions, are designed to absorb or reflect the sun’s UV radiation to protect the skin from damage. The rating system for sunscreens specifies a Sun Protection Factor (SPF) value, which can be thought of as a time factor for the protection of skin compared to exposure without any protection. For example, if a person would show visible erythema (sunbur...

One of the most important and toxic heavy metals in wastewater is chromium. Cr (VI) is released from different industrial operations, including metallurgy, leather tanning, paint, textile industries, chemical manufacturing, pulp production, ore and petroleum refining, metal corrosion, electroplating products etc. Hexavalent chromium is toxic, carcinogenic, probably mutagenic and highly soluble....

In the present study a simple, rapid, sensitive, and cost-effective stability indicating UV- spectrophotometric method was developed of doxycycline hyclate in bulk form validated as per ICH guidelines. The stability-indicating based on forced degradation reactions drug under different ICH-prescribed stress conditions like acid, alkali, neutral, oxidation, thermal, photolysis. absorption maximum...
