The present invention relates to compositions and methods for treating water to reduce the phosphate level thereof and control the growth therein of algae and other microorganisms by treating the water with an effective amount of a composition containing a lanthanide halide.

Lanthanide halide water treatment compositions and methods

The present invention relates to water purification compositions comprising silver and a second material, such as aluminum or zinc metal, to methods of treating or purifying water using this composition.

Silver self-regulating water purification compositions and methods

The present invention relates to a solution and method for plating tin, lead, or tin-lead alloy deposits which contain a co-deposit of fluorocarbon particles to provide a lower-friction solder-type deposit which reduces insertion force and fretting corrosion in separable electronic connectors. The fluorocarbon particles have a size between about 0.1 to 1 .mu.m in diameter, and reduce the coefficient of friction of the resultant deposit to 0.8 or less. Also, the deposit has excellent mechanical properties and can be successfully soldered.

Low friction solder electrodeposits

Heteroaromatic compounds having at least two nitrogen atoms may be used to regulate consistency of alloy content and of deposit thickness. Modified nonionic surfactants which lack terminal hydroxy groups are used as grain refiners having low tendency to cause foam build-up in electroplating baths. Dioxolanes may be used to produce deposits having, as desired, a white uniform matte, a semi-bright plate, or a mirror bright surface. Antioxidants are used to prevent oxidation of divalent tin.
